I recently bought my 05 avalanche. When I try to plug into the trailer light harness I get nothing. I have a 7 wire pole with the 4 flat adapter. I get nothing, I'm trying to hookup a led light bar to it, but I get nothing. Fuses are all good. Just getting frustrated on what I can do!

to confirm:
no power for 6 of the 7 pins?
-were the trailer turn signal fuses part of the fuses checked?
-are you sure your testlight or dvom has good grd when checking for power?
-did you check at the 7pin terminal or at your 4pin adapter?
