Thanks for that. I note I nearly had to wait.

Do you need a 20 amp switch? If you're switching anything like that sort of current I think you should use a relay.
However, to fit a fan override switch all you need to do is put a switch across the 'otter switch' terminals (routed into the cabin obviously...).
I intend to use a relay - I have a couple of spares - but I thought I'd be specific. I didn't want to run a new cable through the bulkhead as when I've done this in the past I've occasionally caused a leak.However, to fit a fan override switch all you need to do is put a switch across the 'otter switch' terminals (routed into the cabin obviously...).
To be honest, you don't really need one.
I had one fitted by Hawthorns as part of their desperate attempt to cure my overheating problems back when I got the car (back in 2001).
However, once Dave Batty had got his hands on the car and replaced the otter and thermostat with lower temperature versions and fitted a re-cored rad, I never needed the override switch ever again.

I've had no overheating problems as such. I ran for four hours in London Thunder with the fans on, but I've found with previous cars that if you turn on the fans when you first hit a traffic holdup you can keep the underbonnet temperature more reasonable. I've got an early Chim with the smaller vents and can't help thinking that they were changed for a reason.I had one fitted by Hawthorns as part of their desperate attempt to cure my overheating problems back when I got the car (back in 2001).

I've fitted them before on other cars, a Rover 420, Scimitar and a Ginetta G32, and liked the reassurance.
