Troubleshooting T-One Wiring Harness 118265 on 2013 Honda Pilot

Question:

I installed the harness on a 2013 Honda Pilot, The install was easy but the problem I am having is the tail lights work but the directional s and brakes do not. The is no power coming to the harness? I have checked the fuses and they are fine, I have also added a new ground line under the vehicle. Ab=ny suggestions what else to look for?

With the T-One Vehicle Wiring Harness for Factory Tow Package - 7-Way Trailer Connector # 118265 since you know that power to the harness is an issue, the fuses are the first thing to check so you are on the right track. Check both the vehicle fuses outlined in your owners manual and also the mini fuses on the harness. Next I'd check each connector to check for bent pins and secure connection.

Finally, I'd pull the relays and swap them. If the working functions change, then you know you have a bad relay and can replace the faulty one.

If all that fails then you will use a circuit tester like # PTW2992 to check wiring function power at each connection point to see if there is a bad wire in the harness.
