Video Transcript for MaxxTow Magnetic Tow Lights Installation

Today, we're going to install part number MT70097. This is the Maxxtow Magnetic tow lights with red and amber LEDs. A couple of things to know that this is a 4-way flack connector and has a 20-foot long harness. In addition, we'll also be using part number PK12716. This is a part 7-pole to 4-pole connector adaptor. Now we'll be using this part since our RV has a 7-pole connecter already installed on it. First off, let's go ahead and use our pole adapter to change our 7-pole connector to a 4-pole connector.

Over with the lid is keyed when you just slide it in until its lid snaps down on top of the key. Let's go ahead and put our tow lights on our vehicle now. To install the lights, I'll start at the back of our vehicle. They're both magnetic and you may have stickers underneath that says, "Do not remove" because this will protect your paint. Now there's a left and right for this guys. Yellows are left turn and the green wire will be our right turn.

Let's simply put them in place for now. Now I'm going to attach this to the metal on the roof. Of course, you want the red facing back. inaudible 00:01:22 access right here depending on the width of your vehicle. It's good idea to go ahead and lay out everything first then tidy up your wires last.

We'll take the 4-pole in now and route it towards the front. We're going to follow the roof rack all the way up to the long side. We'll route it over our roof, take it for a slack as much as we can. Now, I think we'll do is we're going to ahead and just open the hood and slip it underneath. We're going to pull in our access out and then we'll go ahead and shut our hood. Stay away from the latch though so you dont damage the wires. Probably a bad idea to slip underneath the windshield wiper but not under the blade just 1 more thing to help hold it in place.

Now, the tow bar here is a black hawk 2 all terrain tow bar. It has a built-in rack. This 4-pole will actually fit inside here. As long as you have enough room for your safety cables to go through as well, probably be a bad idea to use this. Then, we'll go ahead and plug in to our 4-pole adapter. Make sure you have plenty slack to inaudible 00:02:56 and we're ready to test it. First, a red light circuit, our left turn, and our right turn and then our break signal. With everything working, let's go ahead and tidy up the wires. There's a variety of ways to doing this. This is largely at the personal preference. Some quick and easy we're just going to use some zip ties. I think it would be a good idea is go ahead and just take up our cable like this, put it around the light, close to our wires going upfront and we'll just zip tie right through our roof rack here. It doesnt have to be super tight, you would need some room to get underneath there and cut them when everyone takes this off. Also, you could use probably like a hook and loop strap as well to do the same job and probably would look better too. Now, we'll go ahead and take it you for a test drive and see how it would work. That does it for our review of the red and amber magnetic tail lights from Maxxtow part number MT70097. .

I purchased this product to replace a defective item and it appears that it will not fail the same way the previous one did. The old one would push one of the contacts back into the unit so it would not make connection. 269473

This adapter comes in real handy when you get ready to leave the boat ramp after a great day on the water and find your lights not working. Unfortunately the little flat connector looses contact occasionally because of wear and corrosion. Just plug this adapter into the barrel socket (on most trucks) and now there is a fresh and clean connection. I have only used mine twice so far to get me home, so I could repair my truck plug, but I was real happy to have it when I needed it. 369481

Although I am commenting on this product, I actually would like to comment on the following products. I purchased a brake system, tow bar, base plates and wire harness from etrailer. All of my orders were filled in a timely manner. When I reached out for technical assistance, the advisors were readily accessible. All of the products were installed by me. All of the products were very easy to install by using the video and instructions. 337851

This product has been great. I purchased the multi-pin trailer wiring kit, and 4-pin adapter plug. By also purchasing the vehicles specific wiring harness, instalation was quick and easy! I chose to mount this through my bumber, instead of using the included bracket for a more factory finished look, and to avoud ripping off the mount while on rought terrain. This system works great and is much more affordable than factory parts. I highly recommend! 345641

I put the kit in this morning. It probably took 15-20 minutes plus the time it took to drill the hole for the receptacle itself. I have two comments. 1. I had put the module in the place directed and then realized that I had two fuse plugs in the box, so I took it back out and put those in. 2. It is quite difficult to get the "cap" off the wiring under the rear bumper. I probably struggled with that more than any other single thing. After completing the job, I plugged the 7 to 4 wire converter in and hooked it to one of my trailers and everything worked the way it was supposed to. Honda is really ripping people off with what they are doing. Please see my previous email to you. Thanks for your great product, You can bet that I'll be sending business your way, 78548

Wiring harness was easy to install (less than 3 minutes) and the 7 blade to 4 pin adapter was exactly what I needed. I did not take pictures but I didn’t even need to dismantle my dash panel to instal the harnes/ cable. Easily slid behind the dash pane under the steering column and had just enough slack to plug into the Teconsha Prodigy P2 EBS controller I already had with no hanging slack to get in the way of the brake and gas pedals. Would recommend both products to anyone! 529832

  • Recommended Trailer Hitch, Wiring, and Transmission Cooler for 2017 Dodge Durango
  • I am happy to get your 2017 Dodge Durango set up for some towing! Starting with the trailer hitch, I recommend the Draw-Tite Class III Max Frame Round Tube Receiver Hitch # 75713. This Class III hitch is custom-fit for your Durango, which means it will use existing holes in the vehicle's frame for a no-drill installation. The hitch itself features a towing capacity of 6,000 pounds and a tongue weight capacity of 900 pounds. I definitely recommend checking your copy of the owner's manual...

  • Recommended Lighting Kit for Bike Rack
  • For your bike rack, I recommend the Lets Go Aero LED Light Kit for GearCage4 and BigBoss Railed Cargo Carriers # H01540. This will easily work with your factory trailer connector. If you don't have the separate 4 way connection, then you can use adapter # PK12716.

  • Recommendation for Installing 7-Way and 4-Way Connector on 2017 Toyota Tacoma without Tow Package
  • I do have a solution for you, however there is not currently a wiring harness available that will plug into the factory ports on your Tacoma and provide a 4- and 7-Way connector. What I recommend doing is going with the Tekonsha Vehicle Wiring Harness # 22117, which will connect to the built-in ports located behind the truck tail lights and includes everything needed to install the fully-functional 7-Way connector. This is confirmed to fit your 2017 Toyota Tacoma. From there, you...

  • 4-Way Trailer Wiring Connector Recommendation for 2015 Porsche Cayenne
  • To install a 4-way on your 2015 Porsche Cayenne I recommend the ZCI kit part # 119250KIT as it installs without any splicing. 4-ways don't have doors so in case you have a 7-way and need an adapter to give you a 4-way you'd want the # PK12716.

  • Recommended Flat Towing System For 2017 Chevy Spark With Manual Transmission
  • According to the 2017 Chevy Spark owners manual, only the manual transmission vehicles can be flat towed. Automatic transmission vehicles can only be transported with all four wheels off the ground on a trailer. If you have the manual transmission, then I recommend the Roadmaster EZ4 Base Plate Kit - Removable Arms # RM-523185-4 if you don't have active air shutters. This installation should use the Loctite Threadlocker # LT37420. For a tow bar that either stays with the vehicle...

  • For your 2015 Nissan Frontier Pro 4x, I have looked through your list to put a tow package on your truck and it is solid, but I have a couple recommendations based on preference. The Tekonsha Prodigy P3 # 90195 is a great choice and a personal favorite. It will connect with the wiring harness # 3050-P to an already factory wiring harness. That factory wiring harness is located underneath the dash, to the left of the steering column, taped to another harness near the emergency brake...

  • Per the manufacturer, you can both flat and dolly tow a two wheel drive 2008 Ford Edge. If you have the all wheel drive model, you can only use a flat towing setup. For both the two and four wheel drive models, I recommend flat towing your vehicle with four wheels down as this will be the best option for frequent uses. For a flat towing setup you will first need a base plate kit such as the Roadmaster XL Base Plate Kit part # 4408-1. The Roadmaster base plate kit has a removable arm...

This will simply connect to the 4-way flat giving you the functions of running lights as well as brake lights and turn signals on the trailer. You will need to connect the grounded ring terminal wire for these functions to a bare metal surface. What it will not have unless you connect the remaining 3 wires on the adapter is the electric trailer brakes (blue wire), reverse lights...

  • Recommended 7-Way to 4-Way Adapter for 2018 VW Atlas
  • To convert the 7-Way on your 2018 VW Atlas to a 4-Way, I recommend using the Pollak Adapter # PK12716. This will plug right into the Pollak 7-Way on your vehicle and provide you with a 4-Way flat on the other end. It also features a nice tethered cap to protect the connector from debris and corrosion. I have attached a short video demonstration on this adapter that you can also check out.

There is no wiring included with the connector, as it is intended as a plug-and-play installation.

  • There are hitch extensions available but the Curt Combo Bar # C49360 is not one and would not work in that manner. The best option is the Reese Hitch Extender for 2" Trailer Hitches # RP11004 because it is 18 inches which is the longest available for standard 2" trailer hitches. It is important to note that the use of any hitch extension will reduce the capacity of your truck's hitch by 50 percent.

  • Turn Signals are Dim with Brake Lights Applied on Magnetic Tow Lights
  • It doesn't sound like to me that there is anything wrong with the lights or wiring. The turn signal and brake light are both carried through the same dual filament bulb. The circuit associated with the brake light will generally be brighter than the circuit for the turn signal. I recommend switching to an LED option which will make the turn signals much brighter when the brakes are applied in comparison to a set of magnetic tow lights with an incandescent bulb.

  • Wiring Adapter For 2009 Porsche Cayenne With 7-Way Connector Towing Trailer With 4-Pole Connector
  • If the trailer you are planning on towing has LED lights, the adapter you can use is part # TR20141. This adapter is needed because you have a bulb-out sensor on your Cayenne. When you use a trailer with LEDs, they draw so little power and cause the Cayenne to think a bulb is burned out. If the trailer has incandescent bulbs you can use a 7-way to 4-way connector like part # PK12716. I have attached links to product review videos for these adapters you can check out.
