RobertZ34 Posted November 30, 2013 Report Posted November 30, 2013 Just about finished with my wiring harness for a 3.4 DOHC Fiero, but I have three leftover wiring connectors that I can't identify. They came from the 3.4 DOHC wiring harness, but did not go to the ECU, they either went to the bulkhead connection or the RS electrical center. Just need to know what they were for if possible. Thanks in advance! 2-pin, green and brown wires: 3-pin, only 2 pins used, one yellow w/black stripe, the other black w/ white stripe (Note this is not the DIS-CSP connector). Single pin, red wire, came out of the harness near the auto trans connectors and the O2 sensor wire: Quote
GOT2B GM Posted November 30, 2013 Report Posted November 30, 2013 red one is fuel pump test lead Quote
White93z34 Posted November 30, 2013 Report Posted November 30, 2013 Top one is the AC compressor plug, (MAYBE a 5 speed VSS plug??) middle one looks like it could be for the radiator level sensor Quote
Imp558 Posted December 1, 2013 Report Posted December 1, 2013 A/c Clutch, Fuel pump prime/test, if the yellow wire has black tracer. it's coolant level, no tracer is consistent with a CTS. Quote
