The wires for the thermo fan go into the dash AFAIK (well as far as i can see anyway), does anyone know where they actually end up?

I'm just clueless as to weather or not they will need to be wired into the ECU to work or if they will just work as they are :s

I presume they will be an output on the ECU, because that's what you'll be hooking them up to on your Adaptronic. Temp sender from radiator coolant is an input into ECU, ECU performs calculation whether water is above heat tolerance and triggers the fan relay.

Awesome. Just wasn't 100%.
Well I've found said wiring colors for the thermo fan, and i have a relay dedicated for it. so it should be sweet.
Even though Jason has explained it 45069783409687309568 times, I'm still a tad :confused: with the 5 pin relays. The 4 pin relays I find easier to work but he insisted i use the 5 pin. When I'm up to the relay bit I'll post up what i have to work with in the hope someone can make some sense of it.
Thanks Lucy

They are ECU controlled together with the sensors. One will active also with the aircon when it is on.

You can actually bypass this if you are rewiring and simply have them come on when the sensor triggers a relay. I have a Magna temp sensor in the Fairmont so when she hits the right temp, twin fans come on.

This is what i have so far with the help of nick..
pretty sure this is right
Oh, Relay 1 is to run injectors + the 2nd loom, relay two and 3 are for the thermo fan and fuel pump

Fuel Pump MUST run off the ECU through the relay. If you have a split fuel line or a crash, the fuel pump MUST stop when the engine stops. DO not risk it, you will end up like Booya did all those years ago

Isn't that what the last Relay is doing? AUX 8 controlling (or whatever bloody output it is) the fuel pump? or have i missed something

So stupid Q but should i be right to go with these how they are?
