Electrical problems

Hi! I bought a 1990 fullsize jimmy for a good price but it has some problems. The person that had it, burnt up the wiring in the engine compartment and I'm trying to put it all back to gather again, but could not find the connectors for the oil pressure switch, AC compressor, or the washer motor and pump.Does anyone know a good website to get these type of things besides trying to find them at a junk yard. I put a painless wire harness in it and got it running, so the wiring is there so I just need the pigtail connectors.Thanks for any help.
