I am fairly certain that my truck had one of these trans from the factory, but the PO removed everything except the lockout cable and the relay (still mad about that because now I need to find one ). My relay is mounted to the inner fender right under where the proportioning vale is. I have also seen a 65 c10 with this trans from the factory and the relay was mounted on the firewall between the MC and the recessed area for the engine. Kinda right where the PO ran that black wire for the trailer brake controller that was added on in the 90s ish. Sorry I don't have any better pictures, I'm in college and the truck is at home waiting for me to return so that I can finish the engine swap.
