How to Install a Wiring Harness for a Trailer on a 1994 Ford F150

Today we are going to install part number 118316 from Tow Ready, and this is a T-1 connector we are going to install on a 1994 Ford pickup. This is the point in the harness that we need to split apart and attach our T connector. It is right behind the bumper on the drivers side. There is a little button you push down. It is kind of hard to see on the end. You push it down and it comes apart. And you just reinstall the T connector in the middle of it and then make sure you clip it back together. And it might be a good idea to go ahead and use a zip tie to tie it off somewhere, and that is pretty much all there is to it. Just route your 4-pole wire where you want it along the frame and out by the hitch. Just zip tie it to secure it to the frame and keep it from bouncing around. Then we can route our wire out to the hitch. We will just put it by the chain loop here.

And when you are done with the hitch, make sure you tighten up the spare tire bracket if you had to loosen it to give you some room. All right, and there you have it for our install of part number 118316 from Tow Ready on our 1994 Ford F-150 pickup.

When using this part and wanting to wire up a break controol with the plug and play wireing hardness how do you wire the 7 prong plug to this part

The Tekonsha # 118316 that you referenced will provide you a 4 way trailer connector on the back of your truck. For trailer brakes you will need to additonally add a 7-way connector using part number ETBC7 at the back of your truck, and for the dash-mount brake controller itself you can use the Draw-Tite # 5535-20127.
