I'm hooking up an aftermarket coolant fan relay with it's own temperature sensor and temp. adjustment. I know where I need to connect everything except for a 12v ignition source... I have no idea where get that from. Any ideas?
The only old wiring i see is 4 wires going to a connector that used to go to the fan relay... A thick black and thick red on either side with 2 wires of unknown color in between.
