I have a 05 with the tow package. I purchased it used and they guy that had it before me took the relays. I purchased new ones and installed them. I cannot get the right blinker/brake light to work. The light works fine on the trucks tail light, just not getting anything out of the 7-pin. The left and running lights work fine. I traced the wire from the 7-pin to the fuse box and there is no visable damage. I have new relays, and the 10amp fuse under the hood by the relays is good. Does anyone have a wiring schematic for the brakes?

Thanks

Swap left and right relays to see if the symptom moves.
If it does, you have a faulty relay.

I forgot to mention I tried that as well with no change. I will look at the column for fuses next.

Probably the fuses at the BCM/steering column.
The 05 only have one relay so no swapping left to right.

I remember reading that only 2 of the 3 relays are needed, but I swapped them just in case. I guess the other one will just be a spare. I am about an hour away from working on the truck again. Are the column fuses blade style?

Thanks

Found it. Blown fuse for the right. The jackleg that did the work on my truck used electrical tape on it and wrapped everything. Thanks for the help. All good now. Will be putting my firestone air bags on next week!
