im trying to finish up and get my sr running before the 28th of this month! and bumped into another problem!

i can't find the TPS plug anywhere on the harness! isn't it supposed to be between the CAS plug and Coolant temp plug? there is a plug there but i dunno what it goes too?

it looks really similar to another plug on the harness

Automatic harness? Chase the wires back to the ecu, you need (power 5v) signal and ground. If you're using the manual TPS!
I forget the colors but it an easy DIY'er.

ok so i just snipped off 6 prong plug, now i have 6 wires and only 3 prongs on my tps on my engine

i know i use the white wire and black wire, and what else? i have green/blue stripe, light green/red stripe, yellow/white stripe, and light green/black stripe wires left, out of those which do i use?

Forget about the colors of the wires for now! Get your fsm, or wire diagram for the ecu you have. Find the pins on the ecu plug that correlates to the tps. Pin20 tps signal and Pin37 tps power, matching wires to the pins.
Then test continuity on the black wire to any ground connection in the harness to verify its the ground.

The colors may or may not be:
lg/r ----- tps power
white ----- signal
black ----- ground

yeah im pretty sure your right, thats what i've been readin on other forums

does it it matter where i place these wires on the 3 pronged tps sensor?

Yes, but I can't even picture the wires in there location right now! IIRC whites' in the middle.

i may just try to find a manual tps plug and wire up white to white, black to black, and lg/red to lg/red
