Not sure if this needs to be here or tech. Please move if I'm wrong.

I've got an 01 ext cab and I am trying to wire my trigger wires. For the life of me I cannot figure out the wiring instructions from Amp's website. I've got 4 trigger wires from the amp controller. (Grey/black & blue/black) drivers side. I cannot figure out where the tan wire is I'm supposed to hook in to the factory door trigger. If someone has a wiring diagram or personal experience please help me out. The instructions from amp are confusing at best about 01 trucks.
