Default hotwire a cooling fan!?!

I was just trying to figure a good way to rig a switch to my passenger side cooling fan. The stock on/off degree settings are a little higher than I like, and the tranny cooler is on that side. I'd like to get a jump on the computer. Is there a way to set up a toggle switch so when switch on the fan is on full, and when switched off, returns to normal computer operated funtion.

I should probably also change the thermastat but I'm not sure what to get for a 1995 se sc vin 1.

Sorry for missspellllings and lack of creative engeneering. Need another cup of coffee.

Thanks,

bigt

any switch rated high enough in the amps/volts will hold the fanload.. snce i dont kno what kind of draw the fan pulls i cant tell u a proper sized swtch. it might be better to use a relay........in theroy it will be semi easy to bypass you would just need to set up the relay using the correct wires and then put your switch wired to your relay.....in theory that would be all there is to it... im not very well versed in the bonne elect.system so i cant help ya there, and maybe someone else can add some insight to this......

I wired mine directly. I have a 1994 and the # 7 & 8 relays (farthest toward driver side) control your fans. #7 is high speed # 8 is low. You can get both fans to come on as soon as you turn your ignition key by simply grounding the dark Blue wire on the #7 relay if you wish for your fans to come on high speed, or ground the dark green wire on #8 if you want to have the fans come on low speed. The simplest way to do this if you want them to run in regular mode is to splice a wire into the wires mention above, the wire this wire to a swtich then ground the other termnal of the switch. This way if you want the fans on all the time you flip the switch to the on position and this will ground the dark blue or green wire thus turning the fans on when you turn your car on. When you hit the switch to the off positon the fans will come on when they would regularly come on. If you wish you could wire in two switched in case you want the highs on all the time one day and the lows on another.

Default Computer damage

That sounds like a good fix. I just wanted to make sure there is no risk of damaging the computer or the relays before I start chopping wires.I'm pretty sure it won't but if i'm wrong feel free to call me an idoit.

Thanks,

bigt

Is there anyway to trick the computer into turning them on sooner? Maybe a well placed resistor or something like that? This way you wouldn't have to worry about running your battery down.
