Hi i have recently installed a alpine 6 disc changer in the glovebox of my 75 and have used the vul100310 wiring harness to connect everything up. The cd changer turns on and plays but there is no sound output. If i switch back to radio the sound is there as normal. One thing i did noticed i that on the cd changer plug there seems to be a blue wire going in to wiring block where they connect with nothing corresponding with it at the other end.
Any help would be much appreciated i can get pics of needed
Thanks Steve
