Ignition wiring?

My brother wants me to install a tachometer on his 2005 ZX3 and I have to tap into a wire that is turned on with the key goes to accessory. I would like to know what colors are the ignition 1 and 2 wires in the steering column? Do you guys think that it is the same as the older ones or should i tap in somewhere else? Any suggestions would really help. Thanks

I would suggest getting a Haynes manual, but it's such a new car, there wouldn't be one out, and you are probably going to have a tough time finding anyone with an '05 who can tell you. Your best bet is probably to just call the dealer.

Thanks...I figured it out but it took a few hours.

Which color wire was it?
