Replaced Starter, now, no 12V power at the dash

there is only 2 big wires and one small one. there is a 4th in the same harness that connects to a sensor in the block.

The small wire was all rusted, but i put a new end on it.
all the wires are wrapped up with heat shielding.
I really only unwrapped about 2" of the small wire. I will go out and see if there was another wire with it.

I know the thing has tricked me so far.LOL
