The Painless kit also has an Override ON and an Override Off Toggle switch. Off/Normal/On

That sounds like a pretty awesome kit. Does it cycle on and off with the compressor for ac when the clutch engages?

It does but since my HVAC is still leaking and cycles quickly I disconnected it from the compressor and attached it to one of the AC/Defrost trigger wires. With the Big Ford fans drawing all those amps my Alternator hated it and my Idles paid the price even time they kicked on and off.

I was wondering how you got around that. I triggered mine on a switch rather than the compressor just to keep it simple.

So if I do run mine on a toggle switch, would you all recomend I do both fans together? Or a separate switch or high speed and low speed?

Don't run the power through the switch. Use the switch to activate a relay to handle that duty.

You can use Blue/Green (Ignition #1), Grey/Yellow (Ignition #2), Red/Black (Ignition #3). All only have power when in the run position.
Any chance you have a picture of these wires and location?
