i looked at circuit diagrams for the radiator fan system, and it shows only 4 wires should be coming form the relay (blk/yel, blk/yel, blu, blu/blk). my fan is wired to always be on but i want to put it back to normal. my relay has 5 wires coming from it and i connected them back up but when i turn on the ignition one of the wires starts to smoke and gets real hot. i have 2 grn/yel wires, blk, blu, and a blk/yel. something im missing here?
