I dont really want to run 10ga wire just for switches because it is very thick and stiff. If I only ran 18 ga there is a risk of possibly overloading the max current for that wire.
FYI: i would be running switches for relays to lights and compressor system and the only direct power would be to the CB which only needs 2amps anyways. so nothing of a major power draw.
another point of curiosity looking at the OPs pics, how were you able to crimp in both wires to one terminal? it looks very clean but I cant seem to figure how to do them like that. speaking of which, what terminal (and source if any) did you use in the connector housing you linked?
When I ran my switches, I only used 12 gauge from the battery to power them (now its the remote wire from the stereo 20 gauge wire I think) and I used cat5 to run it to the relays. It only takes milliamps to activate a relay so put the good wire where it counts.
