Just done this on my vs. They run a duel speedo thermo but the blue/white wire from the ecu is still there. When flicking the switch the fan goes straight to high speed

Awsome write up mate. Cheers

What an awesome post. Cheers saved me heaps considering the car cost me 200 bucks cause no-one could fix this problem.

Curiosity

Iv had one of these in every single commodore i have owned (including the one i drive now) and not one has burnt the fan motor etc.. But mine is a different setup i run mine off the thermo fan fuse.. I only use it at lights and in traffic or heating up a bit but i dont turn it on when its hot i turn it on before it gets hot so then it doesnt get hot to start with.. that way its at the operating temp 90% time instead of hot/warm/hot/warm/hot etc if you get what i mean… if anyone is in brisbane area and need help doing one shoot me a PM and il be more then happy to come help you out :spot on:

I have a used 98 VT, which had a relay-fan connection-battery bypass cable on it, but it was so badly attached it fell off, and being as crap as I am, can't rewire it.

You offer assistance in rewiring/wiring in with a switch. Is that offer still available mate?

Awesome mate ! Thanks ! One question though,does the thermofan and ECU go back to closed circuit/self monitor operation after you turn switch off ? I would hate to forget to turn it on one day,in traffic hahaha ! But you have stated that its a bypass switch . Other than that,so gonna do this anyways. Could maybe use a timer switch from an old microwave or washine machine LOL Cheers ! Oh also the wire guage ? Would V105 at least,heat rating wise suffice ?

Wouldnt worry about fan waring out as if you have air cond on all the time the fans on any way, in hot areas like QLD i always have aircond on, in adelaide though im thinking of fitting the thermo now the heat waves have past, GREAT WRITE UP CLEAR AND LOVE THE PICS it helps a lot.

I've done this on my VN with a switch with led. The led lights so I'm guessing there is power and earth but the fan does not come on.

Ideas?
