Hooking up boost guage

[05GTPcmpg]

Okay got the boost guage working with the vacuum but need to know how to light it up. It has two wires one is ground and one is power, i found a good spot for the ground. I see a wiring harness going into the ecm need to know what color I need to hook to, to make the light come on when my lights on the car come on. thanks

just do a ADD A FUSE to the radio fuse or any fuse that would turn on when you turn it on or the headlights.
