Question about 2008 GMC Sierra 2500HD 2WD
I just got my 2008 GMC 2500 HD truck back from the dealership with the same problem. They informed me that the accessory power is no longer hooked up by the factory, that is now the responsibility of the owner of the vehicle. The service tech showed me where the wire was and I connected it to a Stud 1 outside of the fuse box. You will also need a 40 amp fuse for position 68 on the fuse block.
