Main Power Feeds Wires:
 

Quick questions, I'm almost completely done wiring up the truck but need a little info on a few things.

What is the main power wire color/gauge for power windows as well as the power locks.

Which fuel tank is the main tank, I think I was using the passenger side one but haven't activity drove it since '16 I just can't remember. (Need to run the gas gauge wire to it)

What is the location color/gauge to the main power wire to the heater/ac control. Kind of stumped on that one.

As always many thanks for your help and time, it is absolutely appreciated!

On my 75 C10 with dual tanks, the primary tank is on the passenger side. On my 84 CUCV, the single tank is on the driver's side.

If you are just trying to start it, bypass the valve with some hose couplers and remove all doubt about which tank you are drawing gas out of.

Can't help with the other two. Both mine are manual windows. The CUCV is heat only.
