i dunno, you talking about splice into the power wire on the back of the cig?

dont really want to tear into the dash, so i did it the direct way.

I need quality equipment, feel free to donate.

Just pull the bottom of your center console off, where you cigar lighter is...splice into the + and - wires that run to it...simple as that..

As far as the lighted switch goes, the pos from the source (ie...the lighter wire) goes to the PWR plug...the pos on the neon side goes on the ACC plug, and the "earth" plug is a chassis ground, basically any small screw on metal you can find close will work.  I have a lighted switch on my amp and its nice...for my neon, i run independent toggles for each tube, and a master power switch..

(I'm fond of switches)

i wasnt aware you have to ground the neon if the power is coming from the cig lighter. isnt the cig lighter grounded itself?
dream it, build it, fiberglass it

if you are using a cig plug then no ground is needed

I'm wiring neons to a switched 12 volt source (cig lighter) and I'm putting a toggle switch to it. Do i put the switch on the pos. wire? Do i need a fuse? if so what ampage and should it be before or after the switch. Thanks

You should ALWAYS fuses my's like having insurance on your device(s) or wires....but i have a question....i'm about to actually wire 4 neon tubes for a friend of mines soon, and want to make sure i get everything straight before i tackle this job......let me get this straight?....these lil (10") neon tubes have a lil device attached to's a lil box with resistors and transformers in it.....can i cut that out and wire the tubes straight from the actual tube?

No you cannot, what you are describibg is the power supply to step up the voltage to drive the neons, what you will have to do is take case apart to expose the 2 wires coming from the supply to the cig plug itself, solder new wires onto these wires to extend them to your power / ground source, and yes add a fuse.
