Question

Question:

Hey, I purchased the OEM gain brake controller from GMC and they said,yeah, just pop it in and connect the dummy plug end behind the coin holder top left of dash above the 4x4 and lights and poof. It works! Wrong.... Where in the other end of the 6 wire gain plug? Do I need to buy a connector? Do I need to buy a wire? Do I need to buy a different truck?
