Today, I ran the wire that switches the relay for the electric fuel pump... To the fuel shutoff solenoid on the IP.
No more trying to remember to turn on/off the fuel pump. It'll be on and off with the key.
Also glued some pieces of the dash back together again. Leave it to dry/cure overnight, inside, in the warmth, and tomorrow I can put the dash back on.
So tomorrow, I'll probably see what I can do about lubing the speedo cable, then put the dash back together.
After that, it'll be a tossup whether I do the headlight relays, or put the GP controller switch on the fast idle solenoid.
At some point soon, I have to try to get the cable pulled all the way out, on the parking brake, and get that locked on place. I want it that way, when I take the truck back to them. I'll ask them to reattach the parking brake at the back axle, then re-inspect the brakes and figure out what is dragging.
