Another wiring question. Clip number F74 goes to which fan , my setup was previously hacked and currently goes l/b off oil cooler fan (single) to a toggle which couples an e-fan together through main fuse, not proper at all. so im trying to fix that ,rewiring the efan to aarons specs but i dont think the oil cooler fan should be wired to the efan , btw its in between s4 and s5, motor turb and exhaust mani are s5 , uim and lim are s4 , no emissions (wiring removed too) no ac , no aas , no p/s all removals on my car include removing unused wires from harness.

You have an oil cooler fan?
That's hardcore.

Why is it hardcore?

Because it's very difficult to find a decent fan of the proper size and most would consider it unnecessary anyway.

that is hardcore i guess then , it would be even better if the cooling system wasnt hacked

Any efan could be considered a "hack", depending on how pejorative you consider the word to be.

I'm not sure what the problem is here, Aaron's writeup seems pretty straightforward and there are other- even simpler- ways to do this that don't require any interface at all (excepting a +12v tap) with the stock electrical system.

no if you look at the harness there in lies my prob the efan i can deal with easily , I have already replaced coolant temp sensor(s) wiring as it was mostly cut out also ops was cut out of wiring and now y/b and y are hanging at front harness with connector f74 , nothing to connect that i know of. Im not looking for what i could do instead , im bring it back to stock specs , yet there is no cooling fan motor to connect to , atleast not what i see other than the oil cooler fan

The Y/B and Y wires (which my diagram show as connector G-23) are for the fan that went on the AC condenser (if your car was so equipped).
There was never an oil cooler fan from the factory, so that's definitely a "hack" (albeit an interesting one).

hmm intersting , car was equipped with ac , but this is definately f74 of wiring section of fsm available in faq , page 50-38 s4

the oil cooler fan looks stock minus the wiring

OK, I was referencing the S5 diagram, so, my bad.
Happen to have any pics of this oil cooler fan?
I've never seen one...

Harley Davidson radiator fan...It's on my list of things to do. I'd like my oil temps a little lower in traffic and it seems my now larger intercooler end tanks are restricting flow a little. I'm planning on ducting up from the undertray and installing one of these fans.

Oh Jeebus.
As cavalier as I am about mixing in parts from other vehicles, the idea of using a Harley part makes my skin crawl.

Clearly, the fan can't be very big, so do you use two or just one?
