i just got a new wire harness from bill jenkins, but i noticed a extra wire on the harness going to the alternator, my old harness had a 3 wire mutiplug and a gray plug besides the main cable going to the battery, thats it. the new harness has the 3 wire multiplug and the gray plug, but also has a red wire with spade on end of it, besides the main cable to the battery, dont know what this wire is, it has continuity with the red wire of the multi plug using ohm meter. i dont have abs or traction control. was wondering if it connects to main output on alternator. if anybody know what wire this is please help. thanks 95 contour se atx
