Engine cooling fan overide

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.

Chris, these wires are piggy backed onto the otter switch so they're switching the low current side of the relay. I'm thinking I could come up with something to illuminate a warning light if I use a double pole switch.
