2011 DBL Cab TRD Off-Road - on 12v power to 7-pin connector

Hi all -

I've been searching the web (including TW) for days (ok, a few hours per night every day this week) for a solution to an electrical issue. I have a 2011 DBL Cab TRD Off-Road and there is no 12v power at pin #4 on the 7-pin connector. Even with the truck running, no juice. The truck has the factory tow package and there is a relay in the BATT CHG spot in the fuse box. I don't know that the relay is good and I cannot figure out how to remove it.

There is plenty of chatter regarding hooking up 12v power on trucks that do not have it and what to use the 12v pin for, but I cannot find anything about what to do if the truck should have it (like mine) and it doesn't work.

Any ideas. All help is appreciated.

Thanks much,

Lane
