Radiator Fan Configuration Change

Hi, I am wondering whether anyone here has wired their radiator fan to be "always on" with the car running and how you accomplished this? I have a very unreliable trigger for the fan (stock setup) and I just want to rewire the fan to this spec so I do not have to worry about whether it's on or not. The car has a SPAL fan with AFCO radiator setup. No issues whatsoever running hot unless the fan doesn't turn on when it's supposed to.

Just use a standard relay to trigger the power from a key-on connection. VFAQ.com has it on the DSM site, under Electrical.

I recall that there is a wire running to a temp sensor on the rear of the thermostat housing that will turn the fans on permanently if you ground it?

Quoting brisvr4:

Yup. You can intercept either the regular fan wire or the AC fan wire (which kicks on both fans). Both turn on the fan if pulled to ground. This is how the fans are controlled via ECMlink if you use it.

Mark, the fact that we both knew that proves just how old we both are now!
