Video Transcript for Demco RV Custom Fit Vehicle Wiring DM8555002 Review

Today, we're going to be taking a look at the Demco fifth wheel or gooseneck 90-degree wiring harness. This is designed as a universal wiring harness, so that way, it's going to be able to fit many current-model trucks. This is going to provide a 7-way, blade-style connector in the bed of your truck for hassle-free hook-up of your fifth wheel or gooseneck trailer. It also retains the use of the factory 7-pole connector at the back of your truck. Now, this connector can be mounted in the truck bed, sidewall, tailgate post, or wheel well with the included hardware. This does require a 2-inch diameter hole to be drilled in order for it to fit into, and it's got the 4 mounting locations on it that will accept the included hardware for an easy installation. Now, if your vehicle has a bed liner, it will need to be notched, or you could use a longer set of screws and mount directly into the bed liner and body panel.

If you have a spray-in bed liner, then you don't have to worry about anything at all; you should be good just for a simple, basic installation. Now, the wiring harness is going to measure 10 feet long. It's insulated. It's easily going to reach from the rear bumper to the truck bed. It's also going to include your nylon ties to secure the wiring harness up and out of the way. This is designed to plug into the factory wiring harness, no cutting or splicing needed; just make your 2 connections at the wiring harness at the rear of the vehicle, run your wire to where it needs to go, taking the 90-degree portion up to the bed of the truck.

Determine your location, make sure you got your hole drilled. Then these 2 pieces basically just click together, and then you can go ahead and fully install the connector where it needs to be. A really nice design, very easy to use. The unit's going to offer enhanced weather-proofing with corrosion-resistant terminals and rubber-coated copper wiring. Now, this does require that your vehicle has a factory tow package. Here on the connector, the lid has a nice design, easily opens up so you can make your connection.

Then on the underside, it's going to have like a rubber grommet. That way, when the lid is closed, it's really going to prevent moisture or dirt and grime from getting into the connection points. The unit's constructed of an extremely durable ABS plastic construction. One of the things I want to mention is that on some vehicles, you may need to add a fuse or relay to complete all the functions going to the 7-way. Those items are not included, so keep that in mind. That's going to do it for today's look at the Demco fifth wheel or gooseneck 90-degree wiring harness measuring 10 feet long.

  • Comparing Demco 5th Wheel Auto Slide Hitches 21K DM8550038 and 18K DM8550024
  • Demco 5th wheel hitches # DM8550038 and # DM8550024 are both confirmed fits for your 2015 Ford F-350 with the factory installed 5th wheel kit. Both are drop-in installations and both hitches include the automatic slider feature and a generous 14-inches of front-to-back travel for excellent turning clearance. The Demco hitches do include cushioning in the form of polyurethane dampeners that work to reduce noise and shocks from road surfaces. Construction of the Demco hitches is quite...

  • Yes, the Demco Hihacker Autoslide # DM8550024 is the 18K 5th wheel hitch you ordered and will be compatible with your 2016 Ford F-250 6.5 foot bed with factory installed underbed rail kit. The Demco Hijacker Autoslide fifth wheel hitch # DM8550024 comes assembled from the factory to help make the installation easier and quicker.

  • Recommended 5th Wheel Hitch for 2018 Ford F-250 with 6-3/4 Foot Bed
  • Yes, the 2018 Ford F250 will work fine for the 5th wheel you mentioned. I recommend going with the factory rail kit to give you a clean bed when you are not towing. I also recommend the Demco Hijacker Autoslide 5th Wheel Hitch w/ Slider - Single Jaw - Ford Super Duty Prep Package - 18K # DM8550024 which will automatically slide to give you turning clearance for your short bed truck. This particular hitch it designed specifically for your truck. If you prefer a manual slider option,...

  • Recommended 5th Wheel Hitch 2015 Dodge Ram 1500 with Short Bed
  • The best complete system I can recommend for your 2015 Ram 1500 with 5-1/2 foot bed, would be the Demco Hijacker Autoslide, # DM8550040. This hitch slides automatically while you drive to give you 22-1/2 inches of additional clearance for tight turns. It's design relieves you from getting into and out of the truck to operate a manual slider. It has a built in roller-and-guide assembly that allows for smooth, controlled, and automatic movement. This hitch would be paired with the Demco...

  • Recommended 5th Wheel Hitch Adapter for GMC Factory Rail Kit Puck System
  • For your 2018 GMC Sierra 2500 you will need the Demco 5th Wheel Rail Adapter for Chevy/GMC OEM 5th Wheel Towing Prep Package - 6-1/2' Bed - 21K # DM6194 to adapt your factory rail kit to your 5th wheel hitch. If you don't have a slider base on your 20K Reese hitch, you will also want the Reese Square Tube Slider for 5th Wheel Trailer Hitch - 10" Travel # RP30048 unless your trailer has a Revolution or Sidewinder Pin Box to allow you enough turning clearance. You may also want to consider...

This will help with connecting your truck to your trailer. You may also be interested in the Demco 5th Wheel/Gooseneck 90-Degree Wiring Harness with 7-Pole Plug - 10' Long # DM8555002 to add a second 7-way wiring connection to the bed of your truck for easy access to your wiring connection.

  • 5th Wheel Trailer Hitch and Install Kit for a 2017 Ram 1500 EcoDiesel with 5-1/2 Foot Bed
  • Yes, it is very much possible to tow a 5th wheel trailer with your 2017 Ram 1500 with 5-1/2 foot bed. There are just 2 things you will need; a hitch and an installation kit. For the hitch I recommend the Demco 13K HiJacker # DM8550040. This hitch has 22-1/2 inches of travel to provide clearance when making tight turns. A regular slider hitch will not have enough travel and the trailer will likely hit the truck cab when turning. Another great feature of this hitch is that is slides automatically!...

  • Recommended Demco 5th Wheel Adapter For GMC OEM Prep Package And Husky 26K Hitch Compatibility
  • The Demco 5th Wheel Rail Adapter for Chevy/GMC OEM 5th Wheel Towing Prep Package - 21,000 lbs # DM6194 will fit into your 2017 GMC Sierra 3500 Factory Prep Rails and give you the industry standard rails you need for your Husky 26K 5th wheel hitch. This won't give you the 26K capacity of your hitch, but will give you the capacity to pull your 18K Fuzion Triple Axle Toy Hauler. At this time there is not a higher capacity adapter available from any manufacturer. I also suggest adding...

  • Trailer Turn Signals and Brake Lights Not Working with 2011 GMC Sierra
  • Chances are the problem you're having is caused by blown fuses. There are actually two fuses that service these lights. Your truck will have a fuse for the left turn signal and left brake light and another fuse for the right turn signal and right brake light. According to the owner's manual of your 2011 GMC Sierra the fuses are fuses 1 and 3 in your engine compartment fuse box. Replacing these will likely solve your issue. However, being that your truck isn't that old it's more...

  • Recommended Fifth Wheel Hitch For 2017 Ram 3500 With Short Bed And Facftory Tow Package
  • If you are buying a Ram 3500 with the factory tow package we have a couple of fifth wheel options that will work great for you The fifth wheel I recommend for your truck is the Demco Hijacker Autosklide # DM8550035. The head for this slider automatically slides toward the tailgate when you are making turns and returns when you straighten out. The front to rear travel for this hitch is 14 inches. This is a lot easier than exiting the truck to manually pull a lever to release the slider...

  • 5th Wheel Hitch Installation Kit for 2003 Ford F-250
  • Thank you for providing those important details about your 2003 F-250 that will soon be home to a new 5th wheel hitch. Since you have a short bed pickup you will need a slider type hitch to ensure enough turning clearance for your low-speed maneuvers. For a base rail/installation kit I suggest using a custom-fit option that reduces your overall install time and the amount of drilling needed. Since these industry-standard rails kits are not hitch-specific, you can use any brand of rail...

  • How Easy is it to Remove Demco Hijacker Autosliding Fifth Wheel Trailer Hitch from Truck
  • The Demco Hijacker Autoslide Fifth Wheel Trailer Hitch # DM8550034 installs onto industry standard rails. The only issue with removing the hitch from your truck is that it's heavy. The head itself is approximately 40 pounds and base is around 200 pounds. So the issue with removal is strictly weight. To install the Hijacker in your 2016 GMC 2500 you can use the Installation Kit # DM8552011-71. Also, if you'd like to install a 7-way connector inside the bed of your truck to make it...

  • Recommended Auto-Slide 5th Wheel Hitch for 2016 Silverado 1500 Double Cab
  • The 2017 Jayco Eagle 29.5FBDS has a gross trailer weight rating of just under 10K. Page 333 of the online manual for your 2016 Silverado 1500 indicates a towing capacity for the double cab with regular bed that ranges across the engines types from a low of 11K up to 17.7K so the truck seems good to go. I still suggest checking your manual. I recommend a custom-fit 5th wheel base rail installation kit since this type reduces drilling and overall installation time. Demco offers USA-made...

  • Recommended Fifth Wheel for 2010 GMC Sierra 5-1/2 Foot Bed to Tow a 5th Wheel Camper
  • It is possible to tow a camper with a 5-1/2 foot bed if equipped properly, which I can help you do. First thing you will want to do is make sure you find a 5th wheel hitch that is rated properly for your camper. Next with a short bed you will definitely have clearance issues with the truck and camper when making turns so you will want to make sure that you get a hitch that allows for extended travel like the 22-1/2 inch travel that the 13K Hijacker Demco 5th Wheel AutoSlide # DM8550040...

  • To install the 21K Demco Hijacker SL Series Flat Deck 5th Wheel Trailer Hitch # DM6076SL-FLAT in your 2016 F-250 short-bed (without factory rail kit) you will use the Demco installation kit # DM8553000-12. This no-drill kit includes base rails, brackets and all required hardware. The written instructions are linked for you. You can use this hitch as long as it's height allows your hitched trailer to remain level. For a 21K hitch with adjustable height use instead # DM6076SL-21K. For...

  • 5th Wheel Hitch for 2016 Ford F250 Short Bed w/ Factory Tow Prep Package; Proper Hitch Height
  • The fact that you have the factory tow/prep package means that you have many options for fifth wheel towing. If you want a hitch that would drop directly into the pucks, which is the simplest application, I'd recommend the Curt Sliding Q16 fifth wheel hitch, part # C16520-16020. If you wanted to use something that's a bit less expensive, the Reese # RP30051 would work, but you'd need the # RP30156 adapter in order to install the hitch. The adapter would install into the pucks sunk into...

If you friend has the # DM8550022, then you would also need the Replacement Side Plates for Demco Hijacker Autoslide 5th Wheel Trailer Hitches - Above Bed Mount # DM6003 to make the hitch and the adapter compatible.

  • Fifth Wheel Hitch and Rail Kit Recommendation for 2015 Nissan Titan King Cab
  • For your 2015 Nissan Titan King Cab that has a 6-1/2 foot bed it looks like your max trailer towing capacity would be 9,500 lbs like you mentioned. You'd need to go with a trailer that when loaded does not exceed this weight. Since your truck bed is shorter than 8 feet you will need a slider hitch to allow you clearance to make tight turns. My favorite option is the Demco Hijacker AutoSlide part # DM8550034 as it slides back automatically as you make tight turns saving you the hassle...

The hitch head can be removed, which has a weight of 65 pounds. You will need two people to remove or install the hitch or you can use the MaxxTow Hydraulic Pickup Truck Crane # MT70238 to assist with this.

  • Recommended Underbed 5th Wheel Hitch Mount for 2017 GMC 1500 with 6-1/2 Foot Bed
  • There is not a Reese Elite Puck System Underbed kit abailable for your 2017 GMC Sierra 1500. Your best option is to use the B&W Companion 5th Wheel Trailer Hitch w/ Slider - Dual Jaw - 20,000 lbs # BWRVK3400-5W along with the B&W Turnoverball Underbed Gooseneck Trailer Hitch w/ Custom Installation Kit - 30,000 lbs # BWGNRK1057.

  • The easiest 5th wheel install comes with a custom-fit bracket kit that is designed for your specific truck; these reduce the drilling required and substantially reduce the overall installation time as compared to the lower-priced universal kits. For your 2015 GMC Sierra 2500HD I suggest Reese's kit # RP56001-53 which will provide you with industry-standard above-bed base rails. The Demco 5th wheel hitches are the current options we can offer in an auto-sliding 5th wheel hitch. For a...

  • For your 2017 Ford F-250 6-3/4 foot bed, I recommend the Curt A16 5th Wheel Trailer Hitch w/ Slider for Ford Towing Prep Package # C16520-16020. This hitch will give you a nice sliding hitch that will have a 3 point indicator system to confirm proper coupling and will also have the adapter for the puck system in your factory rail kit. It will give you 12 inches of travel between the two locked positions for turning clearance when needed. If you want a hitch that moves automatically...

This adapter for your 2017 Ford F-250 is the Reese Elite Series Underbed Rail Adapter for Standard 5th Wheel Trailer Hitches - 20,000 lbs # RP30156. If you want the hitch that will fit without an adapter, the # DM8550038 or # DM8550024 would be the options. You may also want to consider...

  • Recommended Fifth Wheel Hitch With Adjustable Height Setting
  • I will be happy to explain which fifth wheel will give you the height you need tow your fifth wheel trailer. Yes, your numbers and measurements appear to be very accurate, thank you for being so detailed. We do recommend at least 6 inches of clearance between the top of the truck bed rails and the bottom of your trailer. The amount of squat will vary but estimating 2" to 3" is a fair assumption. Ideally you would want to prevent as much squat as possible and to do this I recommend suspension...

Then for the auto-sliding hitch use Demco HiJacker 18K # DM8550022 or the 21K version, # DM8550037. I have linked videos on all three of these products for you.

You will need a locking plate; use part # DM6026 if you have a standard 5th Airborne pin box; use part # DM6062 if you have an extended type pin box. If you need a wiring harness you can use part # DM8555002 which plugs right in to your existing bumper-mounted 7-way.

  • Recommended 5th Wheel Hitch for a 2005 Ford F-150 5-1/2 Foot Bed
  • I can help explain this evolution to you to help you better understand. The reason short bed trucks like your 5-1/2 foot Ford F-150 needed the sidewinder was because of clearance. A sliding hitch alone wouldn't give the camper/rv enough room when turning to not impact the truck cab. Due to popular demand the Sidewinder was born and allowed many short bed truck customers to tow because it moved the pivot point from a standard non-sliding hitch back 22 inches. The Sidewinder essentially...

  • I reached out to my contact at Demco and for the old FWH-24PA hitch you will need rails # DM6014 as you mentioned that are different from the industry standard size. He said you can use the custom bracket with those rails for your 2017 GMC Sierra 1500, so I recommend using the Demco Hijacker Premier Series Custom Mounting Brackets for 5th Wheel Above-Bed Base Rails # DM8552027 which are a custom fit for your truck.

  • The 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket - Vehicle End # HM40975 has not been confirmed to fit in the cutouts without the bracket, but you absolutely can make the similar cutout so it will work. The oval connector socket does work with a US Car adapter end, so it is compatible with the Curt 5th Wheel/Gooseneck Custom Wiring Harness w/ 7-Pole Connector - 7' Long # C56070 or the Demco # DM8555002 for a 10 foot long adapter. This will give it a really nice and clean look.
