Troubleshooting Right Turn Signal Not Working With Tekonsha 4-Way Harness On a 2021 Honda Pilot
Question:
Hi, I installed the harness without issue. While checking the lights, I noticed the right blinker isn’t working. I used a circuit tester and also connected it to my trailer lights. Please advise. Thanks.

Since the only light not working on your 2021 Honda Pilot with the Tekonsha T-One Vehicle Wiring Harness # 118760 installed it sounds like there may be an issue with the signal coming from your Pilot.
First ensure that the right turn signal is working properly on your Pilot to ensure the problem is not with the vehicle.
Next you will take your Circuit Tester # PTW2993 to check the green wire in the connector that goes into your factory wiring harness for power. If you find that you have power going into this green wire but no power going out of the green wire that is in the 4-way trailer connecter, this is the sign that the Tekonsha harness is defective.
If there is no power to this green wire you will need to test the factory side terminal that the green wire goes into to determine if it has power. You may have a terminal that has pushed out of the connector and is not making contact with the connector if you have power on the factory side. If there is no power on the Honda factory side of this connector there is something else wrong with either the factory harness or something else that Honda will need to have checked out.
