update
Ok...so I got home from work and put the OBD scanner on the GMC. Had three codes on the display, relating to the MAF sensor. I cleared them and they stayed off. CEL now off.
Whew....
So, I guess (on GM products) the low beams stay on when the high beams are on too.
I did order two sets of extensions to run the wires correctly (and out of the way).
