Curt Custom Fit Vehicle Wiring - C56056

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring - no cutting, splicing or tapping required.


Features:

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing of wires
    • Locate connection points behind tail lights
    • Plug in T-connector
  • Comes with dust cap for 4-way flat connector
  • Limited 1-year warranty


Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the tail light assemblies to access this harness.


Once installation is complete, the 4-way connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.

Video Transcript for Trailer Wiring Harness Installation - 2010 GMC Acadia

Today on our 2010 GMC Arcadia we'll be installing Curt T-connector vehicle wiring harness with a 4 pull trailer connector, part number C56056. The first thing we'll need to do is gain access to the back of the Arcadia. With the tailgate open we'll remove these tabs on the tail light and then remove those 2 bolts. With the 2 bolts removed, we just pop the tail light right out of place. Next, pop that tab up and slide the wiring harness out. Repeat that process on the passenger side of the vehicle. Now that the tail light's off we can start running the wiring harness.

The easiest way to do this is to find something to pull the wire up through underneath the car width. In this case we're just using some old air line tubing. Over here on the driver's side of the vehicle we want to fish up the yellow and brown wire. Another little tip here is if the wire seems like it's getting caught up a little bit in there and not pulling real easy you can remove those 2 fasteners and they're the exact same ones that we're on the tail light and allow you to pull your bumper cover back just a little bit, give you a little additional room to finish pulling your wire up. With the wire pulled into place we put those bumper cover bolts back in. Pop the covers back on. This is a plug and play harness.

It doesn't require any splicing so we just take the connector and pop it on to the wiring harness that we just pulled up and this side will go into our tail light. It snaps directly in to the factory tail light. With the wiring harness in place make sure the wiring is pulled out of the way of our alignment tabs and slide the tail light into place. Then we'll finish up by securing it to the vehicle with the 2 screws we removed earlier. We'll have to run the wire under the vehicle to pull up the green and white wires on this side with our other set of connectors. Before we get underneath the vehicle we'll go ahead and run that air line tubing back down behind the bumper.

We'll use that to pull those wires up as well. When running over we want to make sure that we're going to have plenty of clearance over the exhaust so we don't do any damage to the wiring harness. With our green wire ran up through the bumper for the passenger side tail light we can then find a suitable place for our grounding wire which is also attached to that harness. Somewhere right behind the tail light will work. With the ground installed, we can go ahead and hook up our connections and then re-install the tail light upon the vehicle.

Then we can re-secure it with the 2 bolts we removed earlier. With all the wires ran all we have to do is secure it now and we'll use this limb clamp. Now we'll test the wiring harness just to make sure all our connections are working. Start by putting the ground clamp on the white wire or the exposed pole, that's our ground. Then the running lights, the left turn signal, the right turn signal, the brake lights on both sides and they're both working. We know our wiring harness is hooked up correctly. Place the cap on it and that concludes the install of our Curt Wiring Harness, part number C56056 on a 2010 GMC Arcadia. .

I have an Acadia that did not come with the tow package. I had to get an aftermarket trailer harness. etrailer helped me get the correct one quickly. The installation was pretty easy, and only took a bit more than an hour. Now I can safely take my boat on the road and get fishing! 665004
