99 jimmy problem

[Jc1500]

Ok I did a motor swap on my 99 jimmy and when pulling the motor broke some wires and don't know exactly where they go. I figured they were all three grounds but apparantly not. With the ignition on and not started I used a circuit tester hooked it to the ground on the battery and touching two of the wires got a light. The issue I am having is two trouble codes. One is for the fuel guage high input and the other is for evaporative emission system low input. I am figuring I have got these wires off somehow. I had all three on a bolt on the back of the right head. I know one goes there because when I disconnected them the truck would not try to turn over.

All Data DIY has wiring diagrams.

Can you tell us what color the wires are and possibly where they come from?

One is black and another is black and white. The third is a thicker black wire.
