Probably the easiest way to wire illumination is to purchase an add a fuse line from Autozone. You can use a factory fuse spot like your headlights for example, and use the add a fuse kit to feed off of that plug for the power source for illumination.

I apologize but I'm not knowleadgable on the mpguino, I have wired in a vafc which taps wire off of the ecu harness which is under the passengers side lower kick panel in front of the door.
