Try reposting your question. You are not telling the story very clearly. I bet you will get lots of responses!:):)

Congrats on geting it working...

It is nice that the "newer" trucks have all the stuff built in. I have my brake controler harness stuck in the door pocket on my 2000 GMC still. Don't pull very often with it but had thought about adding a controler at one time. Sure beats running more wires from the battery to the back of the truck!

Great! Glad you figured it out. I hate it when these little things slow us down. This site really helps.
