Default Ignition on positive power in engine compartment

What's the best/easiest way to get a positive lead that's on with the ignition in the engine bay to use with my electric fan relay?

I believe that it is the yellow lead to the wiper motor switched

Okay, thanks, excellent.

Any suggestions on where I should put the thermostatic switch? The hole on the thermostat housing and the hole next to it on the intake are used. Where else can a hole that size be found?

I ran my igintion relay for the fans directly from the fuse box. I hate messing with existing wires and/or tapping them.

Usually a tapped hole in each head, your tem gauge should be hooked to the driver head so check you passenger head up near the fire wall.
