I just tried to hook up my VSS Wire, since it was never hooked up and i made more problems. I thought i hooked it up to the right wire, so i put everything back together and now my z1 does not make any sound when you push the buttons and the volume is so low and my stock subwoofer does not go on anymore. i have a 04 g35x. What did i do? I put everything back together. Is there suppose to be 1 harness not plugged in, in the back. I couldnt find any connection to make it. Oh yeah the speed pulse sensor still does not work. when i push the z1 and click the buttons it makes no little sound anymore
