easiest way to do the vaccum lines is how whitecoug said. thats how i did them too. your just basically running the zex box inline with the pressure regulator.
for the bottle warmer, one wire is a ground and the other runs to the switch then another wire comes off the switch to a 12v source. make sure you use a fuse on the wire that attaches to a 12v source.
When we did mine we just ran a larger wire (10 gauge) from the battery for my 12v source for the activation switch, purge switch, and heater switch.
