Has anyone here hooked up a manual switch for the auxiliary cooling fan? This past summer I noticed the temp creeping up when I had the A/C running, and I never did hear the fan start up.

If I short across the terminals on the coolant temp switch, the fan will come on; this works for both the low and high speed fan settings. I don't know if this switch is even working. A replacement switch is pricey, so I'm thinking of putting a toggle switch under the dash.

If you've done this before, I'd appreciate your thoughts on where to wire up this switch under the hood. I could always go across the terminals at the coolant temp switch, but there's probably an easier, more accessible location to wire this up.
