Troubleshooting 4-way And 7-way Connector On A 2012 Toyota Sienna
Question:
We had a friend install it for us, but we cant get the lights on the trailer to work at all, The problem isnt the camper, since we checked it with a different vehicle. He checked to see if the was power coming through, and it is.

You have narrowed your problem down to your tow vehicle. Since your camper's lights work when it is hooked up to a different tow vehicle, it is on your vehicle side. You will need to check the connections of your Adapter 4-Pole to 7-Pole and 4-Pole, part # 37185. This will require a circuit tester, part # PTW2992. I would check your grounds to make sure they are touching bare metal, paint can interfere with this connection. You can use the circuit tester to check the outputs from your 4-way and 7-way connectors.
I have included a product description link, video review links, and a weblink to troubleshoot your 4-way connector below.
