If you convert to electric fan, you will need the basic wiring and switches -- fan, temperature switch, relay, or a master override switch inside cockpit.
You will also need to re-route the hydraulic fan pressure line to bypass the fan and straight to the PS cooler. The pressure line is a banjo fitting, so you will either have to make a new line out of custom plumbing, or chop the banjo fitting, extend the line and route it directly to the cooler. There are many ways of doing it... it doesn't take much work really.

Originally posted by racerhex ive always been told the 92 SE hydrolic fan is way better then any electric!
Yeah, that's true... the stock hydraulic fan is probably stronger than most electric units out there. Stock fan measures 18" in diameter and pushes a LOT of air. It barely robs any engine power (lesser than the added load to the alternator from an electric fan) because it takes pressure from the power steering which is being driven all the time anyway.
I took mine out because I am running a 3" aluminum rad and I have no room to fit the stock hydraulic anymore.

its a LOT of wiring that is near impossible to get the swap done right... i got an engine and ecu and wiring harness from a 94 camry with 1mz and hydro fan. Let me tell you, i wont even try to do that wiring...
i had to wire individual pins on the ecu for my swap, among other things... so i am very good with wiring... and i wont try...
i plan to use an electric fan with a switch setup... just switch it on when i need it, and keep it off if i dont need it.
probably run the switch off of a relay triggered by the ON position of the ignition switch, so when the car is off there is no way i can leave the fan on...
thats like saying listening to your radio will make you lose some acceleration when it is on.......
i think the added stress on the PS pump is more to worry about than the use of power from the battery...cause that actually affects the engine.
I just chose the electric fan cause it leaves you more room in the engine bay. Simple as that. BUT, you do lose out on the PS fluid cooler.
Average power consumption for a engine fan is about 12-14A... that should be enough to add enough load to the alternator and affect acceleration. It obviously has enough load to even cause your idle to fluctuate. When the car is running, all the power usage is supplied by the alternator and not the battery.
On the other hand, I have never notice a power loss when I turn on my stock hydraulic fan. The power steering is being driven all the time regardless if the fan is on or off, and it just diverts the pressure from the PS to the hydraulic fan. The steering wheel actually becomes slightly stiffer as the fan turns on.
