I have my control unit for my boost gauge, but im not sure where to wire it exactly. The 2 wires im having trouble with is Orange (Ignition when on) and White (Illumination when small lamp is on). Now, I wired my Turbo timer to my ignition collum, so Im guessing I can wire Power to the red wire on the turbo timer, and the ground on the black. Where would I wire the ignition and illumination?

The orange wire goes to an Ignition on source. The cig lighter power will work for that (it was green and yellow in my car). The light wire.... anything thats lit. I tapped mine into the gauge cluster illumination wire, the stereo illumination wire will also work, or I guess the best would be the wire directly connected to the switch, if you want to go up under the column and find it.
Check the manual too, there's 2 outputs to start the daisy chain, if you have night dimming gauges make sure you plug the chain into the correct output. (one is constant brightness, the other lets you dim the gauges for night driving so you have a day and a night setting)
