Literally getting ready to wire my fan and I cant get a fan switch from any part houses locallyy soooooo there is a temp switch by the thermostat housing with 2 wires can I splice into that and have it control high/low operations of the fan?

Okie dokie so the little thing next to the big hose with 2 wires coming out of it should be your coolant temprature sensor, not a switch. Did some looking and I think this might help you out some if you know how to read schematics.

It wont let me pull up that page. Ok a sensor so does that mean I could pull my high or low side from there?

No. That just sends the temperature, it does not switch on or off like a temperature switch does.

Here is a link to a thread.. Click on the link in that thread... Once it redirects you there will be a list of wiring diagrams and then look up your motor size and cooling fan circuit... Ex: 5.7L (vin R) cooling fan circuit

This one should be good.

Hey riot936,that's the cts & no you wont be able to use it for fan control,the cts only has one purpose & it's a good one.There are few types/ways you can wire the fans to work properly.Many opt for the easy kit you can get at most auto parts which is a basically a probe you place/install near the radiator & set the desired temp that the fans come on.This system seams to work well with some,I personally have never tried it.There are also some pricey kits you can get but it basically boils down to how much cash you want to spend.You also need to use a switch that works with the thermostat that's in use (192* or 180*),they need work together.You also will need a good charging system and don't cheap out on the wires.
I personally use and recommend a thermostat sending unit threaded into the 3/8" port on pass side head between the middle plugs. Local parts stores will not carry these unless you opt for a BMW switch & mod it.The Taurus fan should be a 2 speed & flows CFM plenty well at both speeds.I would wire in low speed to the switch & high to AC green wire.I would also recommend you mod the Taurus fan to the OEM fan shroud.This will cool the hot block much quicker.
Iv'e had a Mark8 efan for over 3 years this way & never a problem. Mark8's are also two speed,but not low & high they are high and high which do use some juice to turn them but nothing that a properly working charging system cant handle. I use a Summit 890017 fan switch along with a 180 thermostat.I also drilled a 1/8" hole in the t-stat.
Google e fans & you should get many wiring options.I searched for some time & opted to wire it my way.The HD way.Total cost was around $100 give or take a few bucks.

Good luck,

This is my wiring system.I also used Diodes which are not in this pic.

Whats the part # for the switch? What do I mod on the switch? I just ordered a switch from a porsche 900 and am going to build a insert that to go in the upper hose. Alot of guys over on pirate 4x4 use. Similar to this.....
