Fitting an in-car override fan switch,

[The Raiderman]

Thinking about fitting a switch in the dash to switch the fan on when i`m in traffic as temp goes sky high because fan doesn`t seem to come in till i switch the engine off,
Has anyone done this??
where will i have to wire it up to? and can i just bridge the fan switch to make it work or do i need to go from the alternator? and what amp wiring will i need??

new fan switch possibly? 232bhp willy is that na or turbo?

i *think* you wire power in to your switch via a fuse and take the negative off the actual wire to the fan

ive done this mate

basicly u fit a switch in ya dash wereever u want, run a live from battery via a fuse 25amp iirc, to one side of switch then run that live back around from switch to the live on the fan wiring , no need to chop it off etc all ive done is tapped mine in and soldered it up, then run a extra earth from any earth point to the earth wire and there ya go!

total control of fan and mine still works on normal to lol

Never had a problem with mine going above 1/3.

Cool so let me get this straight, run a wire via 25amp fuse from battery to one of the terminals on the switch and then run a wire from the other terminal on the switch to the positive of the fan, where does the earth go??

[richy]

the earth goes from the earth side wire on the normal fan wiring, then to the nearest earth point , mine is bolted near the headlight, make sure u use a good grade wire not just normal 6 amp stuff lol!

its as simple as that! u can then turn it on or off whenevr u want

just bridge the fan stwitch

sorry if this has already been said...havnt read all replies!
