Trailer Wiring Harness Installation - 2013 Buick Enclave

Video Transcript for Trailer Wiring Harness Installation - 2013 Buick Enclave

Today on this 2013 Buick Enclave, we're going to install part number 119147KIT from Tow Ready. First thing we need to do is go ahead and open up the back hatch and get access to the tail lights. Then, we need to remove two plastic covers for the screws. You can pry them just a little bit and they simply pop off. Once we have access to the screws, we'll go ahead and unbolt the tail light. With the screws removed we'll go ahead and gently pull the tail light out backwards and away from the body work.

The wire harness going to the light unclips and we can actually get a full extension of the wires. We can take our light and put it off to the side and with this way we have full access to our wire harness. We're done with the driver side. Let's go ahead and repeat the same process over on the passenger side. Now, we can go ahead and start installing our module. First, we need to find a place.

There's not much room in here so we're going to carve this in the plastic at the bottom and mount it below the tail light. First, we'll go ahead and trace an outline around the module to give us an idea of how much we need to cut out. We'll be using a rotary tool to make our cut out. After initial cut out you're going to have to do a couple of test fits to make sure you have room. After you have the room you need, we can go ahead and install the module. First off, I want to take the four pole and the green wire and run it below the tail light and out the bottom.

Then, with the remaining wires staying above the module, we'll go ahead and slip the module into place. We'll hold it in place with a self tacking screw in this case part number FA1131822 will work fine to hold the module in place. With the module in place we can go ahead and start hard wiring the rest of the wires. We'll be making our connections with a quick splice connectors. To start off, we're going to need a ground point. We'll go ahead and start off our white wire with a ring terminal install that into the sheet metal for our ground.

Then our tester we can use use the same ground for. Next, we'll go ahead and test for our first wire. We'll be looking for the running light circuit. In testing the wires we found out that the red wire right behind the tail light was our running light circuit so we're going to go ahead and connect our brown wire from our module to our red wire. Next, we'll look for our turn signal. In testing we found out that this was yellow wire. So, we'll connect our yellow wire from the module to this wire. Now, also the tail lights on this vehicle are combined so we made all the connections we need here. So, we'll go ahead and tape up the wires. Then our red wire is left over, we'll add a ring terminal to it and add it to the existing ground. Now, we'll go ahead and work our power wire that needs to be ran up to the battery. Just so your black wire coming out from the module. We'll connect the extra length of wire that comes with the kit. Using the supplied buck connector we'll go ahead and connect the two wires. This will be colored black to black then we'll go ahead and secure our connection with some electrical tape. Then we'll run our black wire down behind our panel. We saved this wire for last simply because you can't get access to it once you're down in the bottom. Then we can go ahead and reinstall the tail light. Then, we'll go underneath the vehicle and pull out our wires. We'll go ahead and take our four pole wire and run it out to our hitch. Our green wire, we'll go ahead and run it over to the other side, as far as possible and we'll pull out our black wire but leave it alone for now. Now, to help keep our wires bundled together while I go across the top of the exhaust we're going to use some loom material, part number 459075-1. We'll also be using a loom clamp to help hold it up to, part number A0500. Then, we'll go ahead and zip tie our wires in place. Make sure they're safe and secure and out of the way, not touching anything hot. Now we run our green wire over to the other side, we're going to have to add an extra piece of wire to it. This is a regular piece of 16 gage wire. We'll make a connection with a buck connector and seal it up with some tape. Then we'll go ahead and run it over the exhaust and once again, we'll use a loom clamp and some zip ties to hold it up and out of the way. Then we'll pull our wire up from the bottom to the top. Now, to do this we're going to go ahead and use a piece of air line tubing. Once we pull it up we'll go ahead and zip tie it off to help secure it to keep it from falling back down. Then we'll make our final connection to the tail light. This case our right turn signal was also a yellow wire so we'll make our connection, cut off our excess. Then we can go ahead and reinstall the tail light. This point, we can go ahead and run our power wire up to the front of the car. When we do this we're going to go ahead and route it above the hitch, above the exhaust hanger then over our rear suspension components, then we'll follow the brake lines going all the way up towards the front. We'll go ahead and attach our wire to the air line then use the air line to push up from the bottom to the top. Now, we'll get underneath the hood and pull up the remaining wire. Then we'll run across over to our power distribution box. Due to the fact that the batter is sitting on this vehicle. There we'll go ahead and add a fuse holder. For a fuse holder, we need to cut it in half. One end will get the buck connector and the other end will get the ring terminal. We'll connect our ring terminal and then we'll go ahead and attach the fuse holder to our black wire and then we'll go ahead and attach the ring terminal to the power distribution box. We'll use existing nut for power cable going to it and attach there. Once we have it attached we can go ahead and put the cover back into place then we'll go ahead and tuck our wire underneath the plastic. We'll go ahead and remove the rivets by simply pulling up on the middle of a rivet, releasing it so we can pull them up and out of the way. Then, we'll take our wire and just tuck it underneath the plastic. Then, we'll go ahead and reinstall the rivets. And finally, we can go ahead and install our fuse for our fuse holder. With that, our installation is complete. Now go ahead and try it out. We'll take our light tester and connect it to the white wire for ground and then we'll test the ground wire for running light circuit. Then we'll go ahead and test our yellow wire for our left turn signal and then we'll test our green wire for right turn signal. Now brake signal will be a constant signal from the green and yellow wires. And with that done we're finished with part number 119147KIT on our 2013 Buick Enclave. .

It feels heavy duty and is working exactly as it should. Easy wiring in my 2005 Passat TDI. The most difficult part was bring the 12ga wire from the battery to the rear of the vehicle. The effort was worth it; I have a professional looking install that works perfectly. 78902

Generic kit but with the included test light I was able to install it solo! I could press on the brake pedal and look back at the test light. The green wire was not long enough for my Volt so I had to splice in extra wire. The kit says it will work with LED lights in the car or on the trailer.103644

Very very confusing and incomplete directions, NO way to understand the difference between the red "2 wire or 3 wire setup" Very very annoying, parts missing in, i.e. 12 gage wire, fuze for battery connection. I would NOT recommend anyone with a BMW 135i buy this product, I am very dissatisfied with this confusing and incomplete kit85543

  • What Hitch and Wiring is Need for a 2007 Toyota Prius and How do I Install
  • We carry 3 hitches for your 2007 Toyota Prius, part # 24808, # 11468 and # 60894. I have included links to these hitches and their instructions below. We also have a video of one of these hitches being installed on a 2006 Toyota Prius. Your 2007 Prius can be wired for towing a trailer, but there is not a plug and play type harness available for it. You will need to locate the tail light wires in the trunk, identifying them with a circuit tester, and then splice the harness into them. Ther

  • Brake Lights Would Not Work with Trailer Wiring Plugged Into a 1996 Ford Ranger
  • The correct trailer wiring harness for a 1996 Ford Ranger is # 118325 (does not fit GT models). If this is the harness you are using use a circuit tester like # 3808 to test the wires going into the converter. If the signals on the wires are correct going into the box but they are not correct coming out to the 4-Way then something is wrong inside the converter and it will need to be replaced. If all of the other lights are working then you could have a bad ground on the trailer side. The main

  • Differences Between TowReady Trailer Harness, Part #119147KIT, and Curt PWM Part # C56201KIT
  • The main difference between the TowReady harness, part # 119147KIT, and Curt PWM harness, part # C56201KIT, is that the TowReady kit includes the required circuit tester, while the Curt harness kit does not. However, the Curt does use superior surface-mount technology for the circuitry in the converter box and offers a higher amperage rating for the trailer stop/turn light circuit, 3.0 amps versus 2.1 amps in the TowReady. If you can find out the current draw from your trailer lights that in

  • Trailer Lights Not Working After Install Wiring Harness on a 2014 Kia Sorento
  • To determine if the problem is with the vehicle or the trailer, first disconnect the trailer from the vehicle. Then use a circuit tester like # 3808 or the one that came with # 119147KIT. Test the pins on the 4-Way using the circuit tester while someone sites in the vehicle and runs through the functions. If all the signals are correct on the 4-Way when you test it then the issue is on the trailer. But if the signals are not correct then there is a problem with either the wiring harness, inst

  • How to Install a Trailer Wiring Harness on a 2013 Nissan Versa
  • If you already have the # 119147KIT harness you can use it on a 2013 Nissan Versa but the recommended harness is # C56175. As you have found out you cannot go color for color. You will need to use a circuit tester like # 3808 to test the tail light wiring and then splice in the harness wires accordingly. On the harness, white is ground and attaches to a clean bare metal surface. Yellow is from the left turn signal. Brown is for running lights. Red is for brake lights. And green is for right t

  • Troubleshooting a Hyperflashing Trailer Wiring Harness on a 1995 Pontiac Bonneville
  • I looked into the tail light harness that you said you had installed on your 1995 Pontiac Bonneville and since it draws the power from the tail light circuits I believe that is why your tail lights are hyper-flashing. What I think would fix the problem would be to install a powered unit that draws amperage from the vehicle battery and only uses the tail light circuits as signal wires. For that I would recommend you get a Curt Wiring Kit # 56146KIT. I attached installation instructions and an

The kit includes the 4-pole connector that plugs into the connector on the drivers side frame rail alongside the spare tire and the jumper and relays to activate the factory tow package.
