Engine cooling fan overide
Discussion
Snippet of info for anyone considering fitting the above...
My cars have the wiring already in place for this in the loom (both are '86s though). There was a coiled up length of wire next to the horn on the driver's side, tie-wrapped to the main loom. The wiring colours are the same as those fitted to the fan switch in the rad; and when you connect the wires together the fan motor relay cuts in and runs the fan. So... a short length of wire to a switch inside the car and that's it!
Much easier than cutting into the loom behind the relay board; that was my original plan.

My solution was to run a new live feed directly from the fan terminal into the cockpit with the earth going directly to the battery neg bypassing the loom completley. I then used an old light master switch to connect up the circuit and a small red LED which comes on when I use to switch the fan off and on when needed. I dumped the otter swtich and blanked it off as it is a crap setup.
You could wire in a relay but IMO it's not necessary. The main thing is that works without fuss and gives you control when you need it. The days of listening out for the fans kicking in with prolonged stares at the temp gaugue are a thing of the past.
