Ok things just got stranger lol. When i ran a hot wire to the red wire that goes down to the trans, I started the truck and when i shifted into drive the truck stalled. Tried it again and it did the same thing. So i just put the relay back in and now back to the drawing board.

 

Ok, check the other wires..... With it plugged in, Check the wires coming OUT of the trans. That would be pin 6, (brown), and pin 7, (orange/black trace.) Should see 12 volts on both of those. (with the trans plugged in.)

With the trans UNplugged, a continuity test should show both circuits as being open. (engine running) I am going to guess that you will find the brown wire is grounded anyway....... thus, the engine stalls as soon as you put it in gear. (that wire is TCC control....)

 

I am going give that a try this weekend and let you know what happens ty
