Default connector ids

i have been digging around in the wiring diagrams without luck, so i'll just ask here. i have an 03 truck harness, and there are two connectors that i can't find in the diagrams down by the starter. one has a two pin connector, one wire black and one green. the other connector is a three pin, a black, a gray, and a red with black stripe. any thoughts? i found a two pin with black and green for the coolant level in the reservoir, but that was up by the MAF. i had two other connectors up there too, which i thought might be for AC, but i couldn't find that stuff in the diagrams.

If the plug is directly above the starter than that is the "crank position sensor", the other one sounds like it goes down to the oil pan on the right hand side lower and is the oil level switch plug. If you post up some pics I may be able to help you better.

those sound like the a/c compressor plugs. they are routed underneath with the starter/crank wires.

Spec I think you are correct. That sounds like the a/c clutch connector and the high pressure switch is a small 3 pin circular connector.

ok that sounds kinda like them, the one is a circular three pin connector. that means that i now have two up near the right cylinder head that i have to id, cause i was guessing those to be for the ac. think they were both two wire connectors, but i'll have to check to confirm that. any thoughts on those?

Can you give wire colors? They could be for the evaporative solenoid could be one, the other could be for the MAP sensor toward the rear of the truck intakes. The Evap sensor is toward the front of the intakes. Wire colors will help.

Monte we already got those for him, he is looking for two more sensors. The ones he was originally looking for were a/c plugs.
