car - ae86
issue - not to sure how to connect thermofan
ECU - microLeb

so i know how to get a thermo fan to work via a on/off switch...i personally dont like that idea, might as well just wire the fan to the ignition so its constanly on when the car turns on...

ive got a Microtec running my 20v, it has thermo fan wires (Golberg should know all about this)...think one is power and other is earth...

so i want to know how to run the thermo fans correctly wired to the microLeb.. i have wires + OCR laying around i can us...all i need is a bit more info of what connects to what and what else i need then it should be do-able

please do the needfull :DD

The computer does the switching by providing a earth. But you still need to use a relay, don't make the computer carry the full load.

Use the computer to switch a relay.

batt > relay > fan > earth
Batt > relay > ecu (earth)

Hey guys,
I am looking to have my thermo fan wired up better, using a Microtech LT10s. If I wire it like this diagram, is that all I need to do?

Thanks,
JoJo
