My car is a bit of anoddity that it is an oval dash 1987S with a single cooling fan, the thermo switch in the radiator is 2 wire but it has the twin fan relay in the fuse box.

The engine has been swapped to an S2 but the cooling was left as 2.5 NA with single fan.

I want to upgrade to the turbo / s2 twin fan setup.

Does anyone have any advice on what wiring I will need to alter? Has anyone else had the odd single fan set up on the 1987 S?

The wiring from the temp switch in the rad is only 2 wires, when the fan comes on its high with ignition on or slow with ignition off. I will need to add another wire here for the slow speed, where does this connect into the loom/ harness at the fusebox?

As far as I can see there is only wiring for one fan so unless the factory harness will have been tucked away somewhere I'll need to add a second wire pair to the second fan, where does this connect at the fusebox/ relay side?

Thanks in advance!
