Which wire to tap for 12v Boost Gauge light under the steering wheel?

[CustomMSP]

I just put in a boost controller and need to know which wire I should tap into. I found out that the parking light wire is colored Lt. Green/Black and it's in the door kick panal which I don't know know where.

Thanks.

ok last one I promise! :) I'm not too happy with the install, because of the contrast and the fact that the pod isn't molded in. But I'll live for now. Notice the cover up of the screws with some painted masking tape...hehe
