I've owned a Tundra SR5 TRD which I enjoy a lot. Purchased with 87K miles and now has 122K miles. I've had no problems with it until recently.
I recently towed a dump trailer that, unknown to me, had an intermittent short in it's 7 pin cable.
The short I think is between the trailer brake wire and the right side brake light.
now when I plug any trailer into my Tundra the trailer right brake light is on even with my truck lights off.
I'm assuming that either the controller relay module or a relay is damaged.
If anyone has had this problem I'd appreciated any troubleshooting help you can offer.

Thanks in advance,
MtYota
