How to Install a Trailer Wiring Harness on a 2002 Toyota Tacoma

Alright on this 2002 Toyota Tacoma, we're going to install product number 118379 from Tow Ready. Alright, first thing we have to do is go ahead and remove the tail lights. Right now we'll go ahead and disconnect the tail light from the harness. Alright, we're doing the passenger's side, let's go over to the driver side and repeat the same process. Over here on the driver's side we'll go ahead and take our 4-pole wire and we'll strap it at the bottom, alright. And we'll do the same thing for the T-Connector with the red and green wire.

We're going to take a second to attach our converter box at the back so I have a sheet metal right here. And we'll take our T-connector with the yellow and brown wire. We'll hook that up to the existing factory harness. We'll take our ground wire and we'll run that down as well and we'll attach it to the body underneath. Reattach the T-Connector to the light.

Alright, now at this point we can go ahead and reinstall the tail light. Alright, we'll take our ground wire and attach it to the sheet metal right here. Alright, next we'll go ahead and route our 4-pole over to the center of the hitch following the factory wire harness to do that. And let's leave it loose for now because we've also got to run the T-Connector with the green and red wire across to the other tail light. Pull up our wire harness and plug it into the factory wire harness just like we did before and we'll plug the half back into the tail light and we can reinstall the tail light.

Now we can go back to the vehicle and secure our wires. With the wires secured, last thing that you do is go ahead and test the wire harness with the light tester and we're going to go ahead and try it with the trailer. Alright, and there you have it, part number 118379 from Tow Ready.
