2nd Gen Non-Engine/Transmission Gauge Questions

[JohnMcCarthy]

Installed the 3 gauge A-pillar and the feul, pyro and boost gauges today. It seemed a lot easier to just use a "T" shutoff valve in line with the hose from Genos garage instead of messing with the isolator and filling it with antifreeze and all. Anyway, as far as the wiring, it seemed easy enough for me to find a ignition 12v source by the fuse box. Thought I would ask if any of you know the easiest (most non destructive) way to find a lead for the instrument lites? Preferably thru the dimmer switch. Does anyone know the color code at the harness pass thru? Thanks!

The dash light dimmer is the tan colored wire in the cluster coming off the head light/ dimmer plug.
