Ok I NEED help bad. My 89 vert wasn't heating up with the stock mech fan. (It wouldn't go past the second line on stock temp gauge.)

I went to Mustangs Unlimited and purchased the procomp fan. It has 2 wires 1 black 1 red. I have a 30 amp relay and a new coolant neck so I can put in a temp sender. How the hell do you wire this? We tried for 4 hrs today and the fan would not turn on unless I wired it direct to the battery. Also should the fan be hooked up so it pulls air or blows it toward the front of the car?

Here is the relay the lines won't match up but hopefully someone will know what I mean.

top pin (87) black wire
left pin (86) orange wire
center pin (87a) red wire
right pin (85) yellow wire
bottom pin (30) red wire

Please help to wire, I might just go and spend the 260 bucks and get the black magic fan. I heard they are easy to install. Also I do have a/c and I do not have a low coolant sensor. Any ideas on how to hook this up

If the fan is mounted behind the radiator (like how the stocker was), you want it to pull. Pusher fans kinda suck in general.

Can you provide more info about the wiring instructions (what each wire goes to from the relay)? I would spit out universal info but since they have a provision for the Normally closed terminal, I wanna hold off.

Tell us if you are switching 12 volts to the fan (versus ground). And if the temp sender provides ground (most do, but we gotta' ask).

Good luck.

procomp fan

I have the fan mounted like a stock fan. And the air is blowing toward the front of the car. As for the wiring I hooked the fan red to 12v and the black to ground. I hooked the relay black to ground and the red to to 12volt sorce. yellow wire went to the sensor. the fan won't turn on this way. To get home I hard wired the fan to stay on and the car still over heated. At this rate I should just keep the stock mech fan and eat gas.

Ok, I see that I have the fan wiring wrong, I need it to pull and I set it up to push. that will solve the overheating. But as for the the wires, any ideas?

You are on top of it. A fan pushing air forward will get negated by any ambient air if the car is driving slowly (let alone that the source of air is hot engine compartment air). You're all over that part.

I'll get the rest in a PM reply.

Many fans will run backwards if you reverse the polarity. I have one from a Lincoln Town car that will push or pull depending on how you hook it up.
