I read the mechanical fan delete sticky and i didnt want to clutter it up with my question.
I have two 1995 Caprice wagons, one has a mechanical fan with aux electric fan, the other has the dual electric fans.
i plan on selling the car that has the dual electric fans, but i would love to swap the fan set ups between the two before i do so.

is it possible to do a straight swap between the cars?
my main concern is the wiring of the aux fan that goes with the mechanical fan.

Swap over the headlight harness, computer, electric fans and relays to the tow pack car.

Swap over the headlight harness, computer and mech. fan setup from the tow pack car, don't forget the longer water pump bolts.

Digging up an old post....
I ended up selling the electric fan car before i could attempt the swap.
Today i found a caprice in the junkyard and i was able to grab the headlight harness, both fans, and the fuse block.

So my question is, do i really need the computer from the car with the electric fans or can i just put the harness in and wire the fuse block in my car to match the donor?

You need to have something to tell the cooling fans WHEN to turn on and off independently from each other.

A way of getting around the issue would simply have both fans activate and turn off together, but having them work independently as they should would still be best.

I would consider swapping their positions, primary for secondary. You would figure that in it's lifetime, the primary unit has the most time running on it. By swapping, the one with the least running time would become the primary, and the one most used now would be relegated to secondary use. Might get better, longer life out of them both that way. A little oil on the bearings won't hurt either.

They are two different motor sizes, are they not?

you dont need the computer.i used a new harness from gary at innovative wiring his harness is great. had to run a wire to computer and some to the fuse box. the computer is programmed for the fans even if it did not come with 2 electric fans

This. Gary's kit is worth the money, takes the guess work out of the mod.

Another vote for Gary's fan wiring kit.


Get Gary's headlight relay and wiring harness as well. And the battery cables. They're all great.

Update...
I got the factory harness to work using the factory relay locations too.  I also needed the primary fan power wire from a junk yard car to make it work.
I ran the wire from pin 11 of the ECU through the headlight harness and into the fan plug on the inner fender, and out of that through the factory harness to the relay. looks completely factory.
I even gained cornering lights with the new harness.
the only issue i seem to be having is the low coolant light wont turn off.
gonna look into that soon.

I think my only concern now is the high temp at which the fans turn on when idling. While driving the car stays below the halfway mark, when i had the mechanical fan it would hover at halfway and a little above at all times.

I do think i might purchase Gary's battery cables soon.

Yup, you went from constantly cooling to "on demand" with the electgric fans You could get a chip programmed for lower temps, and keep all that new wiring intact. Or hook them up (rewire) to a temp type probe sensor, available at Advance, Autozone, Pep Boys etc.
