can you hook them both up as one, and just connect it to one plug sensor? anyone have any pics of how they did theirs?

heres mine. Can I run all the wires to the OEM sensor blue and black wire? what about the yellow and green wire, what are those for?

I didnt keep my drivers side fan because it was really bad. Can I just hook all the wires to the pass side oem connector and have them run all the time?

luv2rallye:
I went through your link, plus 3 more that ran off that one. Im still very confused on this. All I know is that I have 2 wires on each fan (1Blue and 1 Black). I also have only 1 connector which is pass side and it has (1 yellow, 1 Blue, 1 Black, and 1 Green). I guess I need someone to dummy paiint me a example on how I need to run my setup to work.
 
This is not that difficult. On the passenger side the blue and black wires should be the ones your looking for.

A motor can spin in any direction it just depends on how current is passed through it. Since you have your fans set up as pullers, you want air to be "pulled" through the radiator.

I assume you have the whole radiator/fan assembly bolted in.
Take the wiring and splice the ends, try the fan blue wire to the OEM blue wire and black fan wire to black OEM wire. If the fan is blowing air towards the engine, it's hooked up correctly.
Repeat for the other fan, just to make sure.

You can wire both fans to the passenger side wiring. Just wire them in parallel.
 
There's two connectors in the engine bay, one for each fan. Connect blue to blue and black to black. I'm still using one of the stock fans, but I'm using one exaclty like yours on the driver's side, from Summit Racing (by the way, they have instructions available on the web site).

My fans come on as they would normally; however, since I wanted to be able to turn them both on when needed, I ran a ground to pin 20 on the ECU. When the ECU wants to turn both fans on high, it grounds pin 20, so I just ran a ground to pin 20 with a switch in between. I used the fog light switch because I got rid of them long ago and had no other use for the switch.

So when I push the fog light switch in, both fans run high until I either push the switch again or turn the car off. If I leave the switch off, the fans still operate normally.

If the fan is blowing air towards the engine, it's hooked up correctly.

Per the instructions, you have to actually flip the blades around AND reverse the wiring to make it a pusher.

I wouldn't do that. These fans draw quite a bit of amps.
 
I have my two 12 inch slimlines hooked up to a toggle switch in the car. Haven't had any issues yet. Here's what your gonna need. Two 12 ft rolls of 18/20 gauge wire. 2 different colors is recommended. A box of 18/20 gauge weatherproof butt connectors, a box of 18/20 gauge eletrical connectors. The type you would use for hooking wires up to a battery bolt. A 18/20 gauge inline fuse, a good 2 way 12 volt toggle switch, a roll of eletrical tape, and a big bag of the small zipties. Pm me if you have any questions. I'll upload a pic next week.

The positive and the negative on the fans can be crossed. Just make sure the fans are blowing air towards the engine. A piece of notebook paper will work. If the fans blow the paper towards the engine, You have them hooked up right.
 
Yeah Paul its pretty easy. I only have one slim fan hooked up on mine and I run it off the AC since I dont have AC in my car I dont have to deal with the cold air. All I have to do is turn it on and boom fan kicks in.
