oil pressure gauge install

[Geof3]

Parts are gathering, now in the planning stage. The functional wiring of the gauge is pretty simple obviously, short of getting the wire ran from the sender up. Not worried about that. The question is, did any of you run a switched hot for the gauge light? Did you pull it from any particular wire? With all the immobilizer stuff, and being somewhat worried about tapping into the wrong wire for some reason, just wondered what you guys did. Seems like a real B!tch to get to the wiring cluster! Thanks!
