Installation

This custom-fit T-connector plugs into your vehicle's factory tow package wiring harness, which is located behind the rear bumper, on the driver's side.


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 Review of Curt Custom Fit Vehicle Wiring - Trailer Hitch Wiring - C55256

Jeff: Hello everybody. This is Jeff at etrailer.com. Today we're going to take a look at this Curt T-Connector Vehicle Wiring Harness for the factory four-way tow package.Now this is a custom fit part. It is designed to fit the 1997 to 2004 Ford F150 trucks with the factory four-way and 1997 to 1999 Ford F250 light duty trucks with the factory four-way and on a custom fit part like this I always like to recommend for you to go to our website, use the fit guide, putting your year and model vehicle. It'll show if this'll work for your application.Now this will provide the four way flat trailer connector at the back of your vehicle to power your trailer's signal lights. And it is designed for use with the factory four-way tow package.

It is compatible with five pole, six pole and seven pole adapters that we do sell separately.And this does connect very quickly and easily. There's no cutting or splicing wires. Basically. You just locate these connection points, which are under the vehicle behind the rear bumper on the driver's side, plug in these T-connector here, ground your white wire, and then run your four-way out towards the back and connect to your trailer.It does come with this nice dust cover that you could install onto your four-way, and you can leave it on there if you prefer. What's nice about is when you're not plugged into a trailer, you can put that cover over the terminals, just like that, and it'll protect them from any damage or from the elements.It does also come with some cable ties to take up any slack in the wiring.

Nice set of detailed instructions that'll describe how to install it. And also this grounding screw. When you go to install this after you make your connection, you do need to ground this white wire. It has the outlet on it. If there's a ground nearby you can attach it, if not you can use the included ground screw to make your own ground, but that should do it for the review on this Curt T-Connector Vehicle Wiring Harness for the factory four-way tow package..

The connector clicked in very nicely. I was replacing a broken factory 4-flat connector, so i unwrapped and cut off the existing wires from the factory connector, snapped this guy in place, re-wrapped it and zip tied it up. If it weren't 35 degrees and windy i would've been done in 15 minutes!

Easy to install. I had to drop the spare tire to get the connection for the harness, yet worked instantly once lugged in. As usual you guys are awesome to shop with.

Wiring needs to be a heavier gauge, other than that it's plug and play.

  • Trailer Wiring Harness for a 2001 Ford F-150
    A connector that has pins in both ends would not be able to plug into anything. Its like a wall outlet, the female end has the slots for the prongs and hole for the ground and the male end has the prongs. All T-connector harnesses work this way. It sounds like you might be talking about a harness that plugs in line with the tail light wiring and has not 2 but 4 connectors total. If your truck did not come with a factory tow package then there would be no where to plug in harness C55256...
