The fan has 3 wires going to it. 12v+ for the high speed, 12v+ for the low speed (both coming from relay), and ground.

here's a link to the instructions pdf for the controller that has several wiring diagrams in it for hooking up everything

 

and you just used the relays in the pdc?

 

No, I tapped into relays in the pdc to get switched power etc to go to the control box. The control box then has outputs for activating other relays (it comes with one) that will turn on the fan.

 

ok. sorry for asking so much this will be my first attempt at doing anything like this. luckily my dad has been around electronics all his life and will hopefully be able to help me.

in the diagram it shows that for a high and low setting i will need two relays does it come with two or did you just use one

 

It comes with one 70amp relay, and I bough another 30amp relay separately

How much is that fan? I think the Taurus fan is closer to 3500cfm iirc. Its also dual speed. If the price is close to the around $75 for the Taurus fan it could be another good option.

 

Ok, I finally managed to get the clutch fan off. To anyone who comes across this post and is struggling, a strap wrench of the chain/vice grip variety is what finally got it for me. $9.99 at Harbor Freight.

Now, 2 questions.

1-Wiring. Being as I have a 2003 that had a stock fan, I wanted to splice this with the stock harness. Obviously this will only work with one speed. If I run it on high all the time, is there an issue? Which color wires are the high and low?

2-Mounting. I bought the plastic strap things. Do you poke those through the radiator fins? Seems a little intrusive to the radiator.

 

for #2 id say yes

for #1, that will NOT WORK!!!!!!!!!! the stock fan draws less current than the aftermarket one, you will melt the wires and put yourself at risk for a car fire if you use those as the driver wires.

if you want it to come on HIGH all the time on the same schedule as the auxillary fan you can use the existing wire a relay signal and run a fused line from the +12v battery to the + side of the fan, then ground it to either the frame or back to the - terminal of the battery.

 

I run the AC all the time, so I am wanting the new e-fan to operate just as the stock e-fan did, which would be on all the time. Could you elaborate on your suggestion to "use the existing wire a relay signal and run a fused line"? Thanks.
