I'm finally just about done with my first from the frame up vehicle. . .a '49 Jeep Willy's Pick-up and the last thing I have to do is wire up the electric fans and I need a little help. Here's what I've got. . .a set of electric fans that had been previously wired together and apparently ready to be hooked up to the wire harness, but weren't ever hooked up and an aftermarket wiring harness. The two fans are wired together and there is a relay. . .right now I have two wires from the fans that need hooked up to the harness (I've already got the grounds connected to the frame and one wire hooked up to the temp. sensor in the radiator. . .still need to hook up the ground for the sensor though). . .I'm pretty sure that one wire will supply power to relay to shut the switch in the relay and the other is to complete the circuit once the switch is shut. . .I'm thinking that the thicker (red) wire is the main power to the relay and the thinner (green) wire is to complete the circuit??? . . .where I'm confused is where each of these should hook up to the wiring harness. . .I only have one wire that is labeled for a fan (there is another wire that is labeled for the electric temp. sensor but I don't think I will be using that one since my water temp. gauge came with it's own sensor). Where should I hook up the red wire and where should I connect the green wire??? I know this is kinda vague and I can explain a little better if needed, but I thought some of you guys would be familiar enough with this stuff to understand what I was talking about and be able to help me out. Thanks!
