I have a 1992 blazer with power windows, power locks and power mirrors. I have removed the power mirrors wiring harness, it didnt work and i didnt want it. I have pulled the power windows wiring thru the door to relocate the switches. So all I am left with is the power lock wires left in the door (and the 2 wires for the window motor, but i know which those are). So besides that connector wires I have another black wire that is wrapped/taped up with the locks harness, and it is getting around 4 or 5 volts. The switch works fine...so I know i have the correct wires together, Just have a rouge black line that I have no idea what it was supposed to be for... Just thought id ask before I start cutting up the tape job and tracing the wire, which will be a challenge since its wrapped with 3 other black wires. Thanks in advance guys!
