Hello all, I'm reinstalling an engine in a 1988 Sunbird GT Turbo (that I didn't take out). I've pretty much got all the engine wiring sorted out, but have a single unidentified wire in the harness where the fusible links and the black start lead (with ring terminal) come out of the harness. It is tan with a white spiral tracer. It appears to have been cut clean - there is no terminal nor frayed strands - just a blunt wire, about 4 inches long from where it exits the harness. I've identified the oil pressure/fuel cut off connector and the knock sensor connector which are also in this vicinity. Anybody know what this tan wire is for?
