Default 2000 gmc 5.3 tps

I still haven't got my truck fixed!
Can somebody link me to a wiring diagram that shows where all three wires on the TPS go to?
My "New" mechanic wants one before we start cutting tape tracing the wires.

There is a black wire, a gray wire and a blue wire, but I cant find where each go to.
I found this diagram, but it doesn't help much.

Tps voltage in factory form is usually around .55 volts at 0 throttle... you can turn the set screw if need be... but I bet it's around that now (unless someone has messed with it)
