I was wondering if anyone would be able (and willing) to post a step by step tutorial on installing a gauge trio in the Xb. Im talking the common water temp, oil pressure, and battery meter, set. I've installed gauges before, but never on a brand new car. Im concerned about doing irreversable damage and I know a few of you have done your own installs. My main concerns are a) where are you running your wires throught the firewall, and b) Where are you placing your sensors? Thanks. -Sam
