Hey man, I had a second console that I plugged in to rule out a broken display. When it didn't light up, I knew it was a problem in the wiring. Just check the connections at every point where you put in a splice on the yellow/gray wire, from the console wiring harness down to where you tapped in behind the radio. Jiggle the wires, check to make sure your tap connectors are clamped down all the way, etc.. hope you get it working!
