if you cut the wires jsut hook all the black ones togther and the other wires are not needed.its a good way to clean up your harness.and if you do that youll have to ground out the temp sensor wire.and your fan should work.if you need more help just pm me.

Is the motor bad? I've replaced mine. Try putting juice from a battery right to it and see if it spins fast.

ok guys figured out what the problem was and how to find and fix it i started at the rectifier 14 volts coming from the red wire then u trace it to the front under the hood wich happens to be the red wire goin to the key switch checked the rest of the wired coming outa the switch nothing after stripping down some wire the black wire was only attatched by one strand so i hot wired the switch by connecting the red and black and grounding the green and capping the kill wire problem solved and thanks to everyone for thier help also
