I posted this once before.... but only one person replied.

i am trying to get my phantom gauges installed in my lotek pillar. i did a search and found a lot of useful info. i know where i am going to put my two senders now i do have a few other questions about the actual wiring of the gauges though.

1) is it safe to connect the wire for the lights in the gauges to the dimmer switch on the dash? i want the gauges to come on with the dash lights but i also want to be able to dim them on those long night time trips.
2)Can i run a single lead wire from the dimmer switch and splice all three of the wires for the gauge lights into that single wire? if yes, do i need to use a larger gauge wire or what do ya'll recommend?
3)what is the best way to ground the gauges? can i do the same as the wire from the dimmer? ( connect all the grounds together and run them all to a single grounding point or do they all have to have an individual ground wire?)
4) wich is the best o2 sensor to tap into for the a/f gauge?
