Flex-a-Lite fan wiring
I'm installing Flex-a-lite 210 fans with the adjustable themostat in my 81. I've got everything hooked up except for the wire that is +12v when the ignition is on. The only wire that I got in the kit is pretty heavy guage wire, is this the correct wire for this connection? Does anyone know of a spot in the engine compartment where I can hook this up?

Re: Flex-a-Lite fan wiring (Ben Taylor)
Just to make this clear, yur asking where to hook the wire to power the relay correct? Not the wire to power the fans? Anyway the fans should be powered(fattest wire) by a direct battery source like the bat wire connection on the back of the alt. I found when wiring my fans a good place to splice into for the power to the relay is the windshield wiper circut. You can slpice into the yellow wire just before it connects to the wiper motor just behind the dist. this wire is hot not only when the key is on, but also hot when the key is in the acc. position. connected like this you can run the fans with the key in the acc position and engine not running. I found this handy when cooling down in the staging lanes at the dragstrip.

The horn relay is where you should be getting your power from.
This is where the alt senses voltage so the alt will respond best if you connect you power there.
If you connect further down the line there will be a voltage drop that the alt cannot sense and you will loose a few volts...
