Hit the wall...

I spent some time this morning tracing out the brake light function from the cab to the taillights. Then I found out the taillight loom I got from a 2007 will NOT work. It's a single taillight setup. Problem I figured out that there are two taillights in the wiring diagram and then started looking for the white/tan lead nope. Not there. Now I'm on hold, waiting to see if the salvage yard has a 2005 wiring loom so I can get the right wiring. The project is on hold for a bit to sort out the electrical for the taillights.
