the reason I'm asking is I'm swapping in a 400 and the sensor thread holes are different sizes I'm using early style heads. will I be able to find a compatible sensor that will fit the bigger holes?

As stated, one is a switch for the aux fan and the other is the temp gauge sending unit (sensor). If you don't care about those functions, they aren't "necessary". Since they are pipe threads, you can probably use pipe bushings to adapt to larger holes.

The wire off the fan switch, circuit 335, is brown. It is spliced with a tan wire from the compressor at a connector. After making it's way through a couple of other connectors, it ends up at terminal "B" on the fan relay as a green/white wire. The fan relay is mounted on the inner wheel well, approximately below the master cylinder.
