I have had my Enclave for 2 months and my Buick Dealer cant get a wiring harness and recpt for it. I dont have a towing package and the numbers of the parts seem to have changed. I am in Florida and this dealer lists part #25845096 for the harness and part# 12191503 as the part for the plug. Anyone know if these are the right numbers? Or what has anyone else used for the Enclave? They put a drawtite hitch on .All I do is pull a small utility trailer or hitch haul every once and a while. Just want the option to pull Any help would be appreciated. I dont want this to go on much longer as I see that the other forums that GM is not paying for the UBEC replacement. My dealer is providing the hitch and wiring.
