Okay dude, thanks for all of your help, as of right now I have the old shroud and fan/clutch removed, I've found the maxi Fuze you were talking about and used it and started the wiring of the thermostatic controller, I went to home Depot and picked up some stuff and I'm going to use some aluminum angle to mount the new fan assembly... also I got some orange sprayed chained to hang my truck "nuts" on the back of the truck... the nuts are actually internal gears from a rear end . Lol side note

So I didn't pull these fans at a salvage yard, I got them new... still decently priced I must add... but anyway if you look at the picture I posted there are 3 wire that come from each of the two fans RED, BLACK, and BLUE... I have some sort of idea that black is ground, red is hot, and blue is some kind of control? Anyway they are spliced together into 4 wires, RED, BLUE, BLACK, AND RED W/BLACK STRIPE... What wire are what? I tried to look it up but I'm not finding anything...

Mornin';

Why'd ye start another thread on this? https://www.f150forum.com/f10/want-f...answer-294990/

That just confuses folks due to lack of continuity, disjointed responses etc, and I think is kinda frown-upon... maybe ask a Mod to merge?

Anyhoo -

Those are either 2-speed fans, or one wire is an RPM sense output.

Can you post a link to where you bought these and/or manufacturerlabel with model # ( sorry - dint read back much in this thread ). This may help find the answer I reckon.

Redneck method is to cut off the connector and use a FUSED 12vdc source, test each fan to find the low/high speed windings. But first, use an ohmmeter to ground on each wire - if one is high impedance, that is a sense wire - the fan windings will be very low impedance.

good luck
