toggle switch for electric fan (84)
How can I hook my (one) wire temp fan switch, to a toggle. That way I can turn my fan on anytime. Is this possible? How can I do this?

It works fine, I just want to be able to turn the fans on at will. The sensor will still come on at 200 and 20 something degrees like it should, If I wire it the right way, right?. It will still work like it should, but I will have the option to turn it on. Sounds good to me. Why not?

If I get a toggle switch and "splice" it into the sensor wire and ground the other wire, then the sensor will still work and even if I forget to turn it on, it will still work, because the sensor is still hooked up. I don't think there is anyway of leaving it on because you can hear it. So the worst that can happen is the fan gets left running

I've done the same thing with my 84 bracket car. I turn the fan on manually while in the staging lanes. After my burnout, I'll turn the fan off. Water temp is usually around 170. I'll make my run without the fan turning on. My car is setup so the fan will automatically turn on at 190 even if the switch if off. Willie

Turning it off, on the other hand, could be a slight problem but the stock fans are hot-wired to accessory, I believe, so it's not like they'll keep running while the car is off.

the on off temps are a function of the fan switch in the left head. The primary side of the fan relay is powered from the acc. Sidr of the ignition switch. Even grounding the green/white wire from the relay ckt #335. Won't run the fan.

I have an 84 so I can tell you for a fact what it does. If you use the two fan wires for a splice, the fan will run even when the key is off. However, if you use the two relay wires, then the fan will only run when the key is "ON". ACC will not run the fan. You'd be better off going through the relay unless: 1) Your relay is broken or 2) You want to run the fans after you kill the engine. I have mine wired straight to ground so it's always on when the key is (because I'm too lazy to run a fan switch)
