I purchased a Hopkins kit that plugged right into the leads on the drivers side in the rear. I knew it was going too easy. No power to the plug. Looking in the smaller of the fuse boxes under the hood, I see what looks to be a spot for a relay under what is labeled towing tail. 1. Any idea what relay to install? 2. Has anyone been this route that could help?

    Going by memory here, so don't take this to the bank, but I remember my '04 Tundra trailer wire relay being the same as the fuel pump relay.

    It's pretty easy to test. There are several relays in our fuse boxes and they all do the same thing. If it's the same dimension physically, it will work fine. Relays are not fuses, there are only physical differences.

    Try swapping out with another nearby relay to see if you get functionality for your trailer harness.
