Can anyone tell me whether the 2 plugs on wiring harnesses which plug into my 2 throttle position sensors are interchangeable? If not which plug goes to which sensor. The electrical wiring diagram I have only shows one tps. I'm guessing one is for open and one is for closed positions.

They are two seperate TPS's, one for the ECU and one for the TCM (Trans Control).

You can put the plugs in either one as I've swapped mine over before without a problem.

Thanks nfghia, I'm just replacing original manifold and throttle body etc with edelbrock which came with only one sensor. I'd better chuck an extra one on.
