Does anyone feel naked without some sort of additional circuit breaker?

The connectors on the PCM are designed for use with 16-24ga wires so there is no reason you must supply the PCM with 18ga wire.
http://www.crosstheroadelectronics.c...7s%20Guide.pdf However a 20 amp fuse provides proper protection for an 18 ga wire and as long as you keep the total length of the wire less than 5' (positive and negative combined) you won't have excessive voltage drop.
I do not have a problem not having multiple circuit protection devices. One at the source is all that is needed for proper circuit protection. I am a little concerned about the use of a fuse instead of a self resetting circuit breaker, however from my understanding the PCM has the capability of shutting off the compressor before it can cause the fuse to blow in normal circumstances so the fuse really only needs to protect the wire between the PDP and PCM.
