2004 Jeep Questions and Answers


  • Trailer Lights Go Out when Brakes are Applied
  • What you describe is a ground problem with the trailer wiring. Starting at the rear of the vehicle, confirm that the ground connection on the Plug and Tow Harness is securely fastened to bare metal. If there is undercoating, corrosion, or grime built up under where you attached the ground, you will not have a good connection. Next, examine the point on the trailer where the trailer connector ground wire attaches. This can usually be found on the trailer tongue. Make sure the wire is in...

  • Blue Ox Tow Bar Adapter for SmittyBilt XRC Bumper on a 2004 Jeep Wrangler
  • There is actually a Blue Ox tow bar adapter for the Smittybilt XRC bumper. It is # BX88304. The other options either have pins that are too large or are designed specifically for other bumpers.

  • Wiring Harness Recommendation for a 2004 Jeep Liberty Without a Tow Package
  • I verified with my contact at Hopkins that the Hopkins Plug-in Wiring Harness, # 42475, will work on your 2004 Jeep Liberty if it did not come with a tow package. He also stated that the factory connection is typically on the passenger side, but it may be possible that the manufacturer routed the connection to the driver side. I would recommend checking the passenger side for a connector before attempting to connect it to the connector on the driver side. One thing that you will...

  • Tow Bar and Accessories for Flat Towing a 2004 Jeep Wrangler Behind Motorhome
  • You can use a tow bar like the Tow Ready # 63180 to tow your 2004 Wrangler, but keep in mind, the tow bar is NOT rated for speeds above 45 mph. If the Jeep has the U-channel bumper with the flat front, you can use part # 40602 to provide an attachment point to the vehicle. In order to run at highway speeds, I recommend using a tow bar like the Roadmaster Falcon 2 Tow Bar, part # RM-520 and base plate kit # RM-521424-4 which is compatible with OEM double tube bumpers. You will also need...

  • Which Way Do Conical Washers Face When Installing Weight Distribution Head to Shank on # PS49903
  • If you are speaking of the conical washers used on the top bolt that holds the weight distribution head to the shank, as shown in the diagram I edited for you, the concave or dished portion of the washer will face inward toward the weight distribution head and away from the bolt head or nut, so that the washer will compress as its tightened.

  • How to Determine if a 2004 Jeep Liberty has a Tow Package to Pick Out Trailer Wiring
  • The most efficient way to determine if your vehicle has the tow package is to take your VIN number to a Jeep dealer and have them run it. They will be able to tell whether or not you have the tow package with that information. Or you could check the wiring in your vehicle to see if the correct connectors are present on your vehicle. Check out the installation instructions I attached that will show you how to access the area. If you have the tow package, or if you find the harness...

  • Does Roadmaster Base Plate Kit RM-521424-5 for Jeep Wrangler Include Installation Hardware
  • Yes, the Roadmaster Base Plate Kit # RM-521424-5 that fits your 2004 Jeep Wrangler does include the necessary installation hardware. Base plates are one of the five basic components for safe and legal flat towing and the linked article will illustrate. You also need a tow bar like the RoadMaster Falcon 2 # RM-520, safety cables like # RM-643, a lighting kit like # MT70097 from MaxxTow and a supplementary braking system such as the Blue Ox Patriot II, # BRK2016.

  • The recommended Thule square bar roof rack for your 2004 Jeep Liberty with factory side rails uses 58-inch crossbars, parts # THLB58 and # TH450. I have linked an installation video showing an application on a 2012 Liberty .

I suggest you check your Liberty owner's manual for any information...

  • Parts Needed to Flat Tow a 2004 Jeep Grand Cherokee Behind a 2007 GMC Sierra 2500
  • In order to flat tow a vehicle, the very first thing you are going to want to do is consult the owners manual in the recreational towing section to determine the correct towing procedure. If you find that the vehicle can be flat towed then you will need 5 items. First you will need base plates on the vehicle being towed or the Toad. The base plates provide the proper safe and secure attachment point for the tow bar. You can use base plates # 1425-1. I have included a link to a video...

  • Difference in Above Bumper and Below Bumper Front Receiver Hitch for 2004 Jeep Wrangler
  • I would recommend to first check with the manufacturer of the hitch mount deer feeder to see if they recommend an above bumper hitch or a below bumper hitch on the front of your 2004 Jeep Wrangler. Depending on the style of the deer feeder you have you might need to have clearance from the bumper, so an above bumper hitch might work better for that application. The installation of the above bumper hitch like Curt Front Hitch, part # 31408, on your 2004 Jeep Wrangler, is listed as...

  • Cargo Net Compatibility with a Rola Roof Mounted Cargo Basket
  • The Rola Flat Strap Cargo Net, part # 59200, will fit your Rola Roof Mounted Cargo Basket, part # 59504. This cargo net uses flat straps with a bungee cord net that allows it to grip a variety of different items. The Rola cargo net provides plenty of strength, but that is dependent upon the type of terrain you are traveling on and the weight of the times on the roof rack. For heavier items you may want to use ratcheting straps like the Retractable Ratchet Straps with Push Button Release,...

  • How Do I Install a Trailer Light Harness on a 2004 Jeep Grand Cherokee
  • To install a trailer light you will want to use part # 118369, a T-1 connector that is designed to work cooperatively with the vehicle computer and wiring. It plugs into a port in the cargo area, behind a panel on the driver side. I have added a link to the instructions below.

  • Do Electric Trailer Brakes Work in Forward and in Reverse
  • Yes, electric brake assemblies will work in reverse. The brake controller in your tow vehicle would still activate in reverse as long as the brakes are applied. The actuating arm of the Dexter assemblies part # 23-27 will apply the brakes when pushed in either direction. That means that in forward or reverse the assemblies will still apply trailer brakes.

  • Will K2 Rampage Snow Plow Work With a 2004 Jeep Wrangler?
  • The Detail K2 Rampage II Snowplow # K2RAMP8219 will fit a 4-wheel drive 2004 Jeep Wrangler. When assembled, the K2 Rampage is 265 lbs, and as long as adding that amount of weight will not exceed your gross axle weight rating (GAWR) then it will not be an issue. To find your Wrangler's GAWR, just locate the "Tire and Loading Information" placard in your Jeep, which according to the owner's manual is located on the lower driver's side instrument panel. The snow plow would be mounted using...

  • Do Transmission Coolers Have to Install Right Side Up Or Can they be Upside Down
  • The Derale stacked plate transmission coolers like part # D13403 can be mounted in any orientation that you need including having the hose fittings down. The line pressure from the transmission will push all of the fluid through the cooler regardless of how it is mounted. My recommendation on mounting this transmission cooler is finding a location that maximizes air flow through the cooler. Ideally, this would be in front of the radiator or AC condenser. Either fitting style would...

  • Which Trailer Wiring Harness Fits a 2004 Jeep Grand Cherokee Laredo with Factory Tow Package
  • In 2004, the Jeep Grand Cherokee either came with a factory installed 7-Way harness at the rear of the vehicle or no trailer connector. The towing prep package may not necessarily include the 7-Way but it could still have the tow package. This sounds like the case for your vehicle. Since it states that it has the towing package, then you will need Tow Ready Custom Fit Vehicle Wiring, # 118381, that you have referenced. You will need to locate the factory wiring harness behind the bumper...

  • Wiring Diagram for a 4-Way Connector On a 2004 Jeep Wrangler
  • Wiring your 2004 Jeep Wrangler will require installing a trailer wiring harness inline with existing vehicle tail light connectors. The Plug-N-Tow (TM) Vehicle Wiring Harness, item #32615, installs underneath the passengers side of the vehicle above the rear tire mud flap. Once you have found the mating connector you just separate it being careful not to break the locking tabs and then plug the harness inline. At this time we do not have a schematic for the wiring harness. You can view...

  • Brake Controller Installation on 2004 Jeep Liberty with Factory Tow Package
  • If your 2004 Jeep Liberty has a factory-installed 7-way trailer socket at the back bumper then brake controller installation will be simple. The controller I recommend is the easy-to-use and reliable Prodigy P2 # 90885. This proportional controller will slow your trailer right along with the Jeep, so you don't get so much of that tug-of-war feeling from the trailer. You will also need wiring kit # 5506 to provide you with the wire and connectors needed to install the controller with...

  • Weight Distribution for a 2001 Coleman Utah Popup Camper Trailer and 2004 Jeep Grand Cherokee
  • If the tongue weight on your camper plus the weight of anything loaded behind the rear axle of the Jeep is greater than 600 pounds but less than 800 pounds, go with the 800 pound system, # RP66153. If you will always be lower than 600 pounds then the 600 pound system, # RP66151, will work just fine. Both of these systems have built-in friction sway control so you will not need to add any. You will need to add a properly sized ball. For a 2 inch use # A-90 and for a 2-5/16 inch use...

  • Brake Controller Installation - 2004 Jeep Grand Cherokee
  • Usually, the blue wire you mention is only ran if the vehicle is equipped with the OEM 7-way connector. I'm assuming you've also found where that wire terminates at the rear of the vehicle, is that correct? If so, you'll need to use a multimeter with some long leads to check the continuity on that wire, to ensure its the same wire. If it isn't, you'll need to run your own brake output circuit. Since you have a 4 pole in place, provided by the # 118369, you can use the brake controller...

  • If you are wanting a 7-way connector at the back of your 2004 Jeep Liberty and you have brakes on your pop-up trailer, and you currently have no connector installed, part # C56175, and part # ETBC7, will do just that. I have attached a helpful article that explains how to install the # ETBC7 you can check out. You will also need a brake controller. I recommend the Tekonsha Prodigy P2 Brake Controller, part # 90885. This is our more popular brake controller because it is easy to install...

  • Transmission Cooler for 2004 Jeep Grand Cherokee
  • Transmission coolers like the Derale # D13504 are not actually vehicle-specific; the largest size cooler that you can fit and properly install can be used but adapter fittings may be required. Derale cooler # D13504 is an efficient Class IV type transmission cooler that measures 11-inches wide x 12-inches tall x 7/8-inch deep. As long as you have space to mount the cooler you're ok to install it. Use adapter # D13028 if your transmission hose has an inner diameter of 3/8-inches; use...

  • Can the Transporter Combi Cargo Carrier be Used as a Golf Club Carrier on a 2004 Jeep Rubicon
  • The Transporter Combi Cargo Carrier would be a great option for locking up your golf bag while at work. You will need to do some measuring to determine if the Transporter Combi Cargo Carrier, # TH665C, will fit on your 2004 Jeep Wrangler Rubicon though. I attached a photo showing all of the dimensions of the carrier. Basically, I am concerned about the size of the spare tire on your Rubicon. Normally the Rubicon and Sahara models have a larger spare tire that could interfere with installing...

I have included a link to installation instructions and a photo of a similar hitch in the same mounting location for you. The front mount hitch makes a great attachment point for a winch mounting plate or tow hook loop, see links.

  • Trailer Lights Not Functioning On a 2004 Jeep Grand Cherokee
  • It sounds to me as if you are trying to say that you have power at the trailer connector but not at the trailer lights. If this is the case you most likely have a ground issue. I would start by checking all of the ground connections on the trailer and making sure they have good solid clean connections. Check the wire at the trailer tongue and check the tail lights connection to ground. Usually the tail lights are connected through their mounting hardware so you will need to make sure that...

The 5th Airborne portion of the pin box means that it is cushioned.
