Installation of Tekonsha Wiring Harness # TK22113 on 2017 Dodge Durango

Question:

I have a 2017 Durango. Everything works other than the infamous blue 12g wire to the green wire on the body harness. This picture is straight from Tekonsha. I got it from your site. I just need to know which green wire. I did read in one of the reviews for the harness that the customer just ran the wire to the fuse box. Im not sure how that would work though. Please and thank you.

The vehicle connection wire isn't as easy as just saying the green wire that is closest to (blank) is the one you are looking for. Each of the green wires need to be tested to determine the correct wire function using a circuit tester or voltage meter.

Once you either connect a brake controller and hit the manual override on the controller (or if you don't have a controller sending 12V power down that pin location), you will be able to put a circuit tester on the green wires of that body harness to determine which one has power when you add the manual override and yet doesn't have power when you don't. This testing will reveal the correct green wire to splice into to connect the blue 12 gauge wire.
