Ok so now that i am almost done with this turbo colorado truck i wire in the black apexi avc-r . i wired it per universal instructions got the wire diagram from chevy for the pcm , find the 12v switch, ground, injector, tps signal and speed sensor. turn on the truck and the avc-r doesnt light up. the only thing that is lite up is the control buttons but the lcd is not working. anyone else have this issue? i knoticed in the back of the book that a line in there says if the lcd does not work kindly repack all of the parts and ship it back to the dealer in wich it was bought. ummmmmmmmm ok wasnt bought local for one and 2 could there be a posible cause elseware?
