what do i hook electrical into so the guage lighting will work with dash lights, and does anybody have a pic of where the fitting goes engine side for boost guage on an 03' ???

 

Easiest place is to tap into the ash tray light.

 

Where your light switch is,you take and remove it and there is
some wires coming out,find the orange wire with a white strip.
This is the wire that you want to splice into for gauge lighting.
It will come on with headlights,it will also work with the gauge
dimming deal.
The way I hooked up my boost gauge.
I got a 12' long nylon tube and went right of the turbo.
go to the hardware store and get the brass fittings you need.

 

Ditto on the Orange wire with the White tracer. Makes it work just like the dash lights. There is a pic on my website showing the boost and EGT probes installed...
