Hey I hope someone can help me on here I'm stumped! I have a 2004 trailblazer and decided to put a little boom in it. So a few weeks ago I hooked up 2 12 inch kickers with kicker amp and had to get the l.o.c. to convert factory to RCA. So I did so and did all the wiring myself and it worked fine with factory deck! Fast forward to today, I bought a pioneer supertuner 3 and got the gm2000 wire harness and hooked everything up perfectly step by step and now truck won't start, won't even crank, nor will radio come on! Tried putting factory deck back in and same results! I've checked fuses and have none blown...SOMEONE PLEASE HELP!!
