Stock fan wiring connector location on a 89 Mustang 4 cylinder and what triggers it?
#1

Im working with 89 Notchback that started its life out as a 4 cylinder automatic. Its had at least 3 or 4 different motors in it but most of the stock body harness is in it. 

I recently put in a 87 TC motor in it using a NA 2.3 harness from a junkyard. I used the stock TC rad and fan shroud but I have not been able to locate the harness connector on it unless im blind. Im guessing maybe it got cut or really tucked away.

Anyone know on fox bodies where the fan wiring should lead to from the fans back?

Worst case I can buy a separate controller and run it off a 190 thermostatic switch for now.

Should come out of the same loom as the headlights. Trace the left light wiring to just behind the radiator support. Don't know if the stock TC fan is a single or two speed unit. Single is 2 wires and two is 3. Same applies to the year of the car the wire harness is out of that you used. And the connector could still be there but doesn't match the fan that's installed.

I found the connector and just for the hell of it plugged it into my secondary fan on the stock TC fan setup and it never kicked on once the car got warm. Debating on troubleshooting the entire cooling system or running a switch for now until I buy a Pimp controlling it with that. This is under the assumption that my fans work.

You might wanna consider testing the fan(s) by jumpering 'em directly to the battery, Ian....before making any further plans based on "assumption".  . [Image: confused0024.gif]
