New radio installed in tahoem audio problems

jbordinhao · 08-07-2007, 09:31 PM

i installed a jensen vm9312 in my 2001 chevy tahoe everything seemed to be working fine but there was no audio. so i hooked up factory radio up and it worked fine. what i found was a second wire harness which seemed to be for the onstar created this problem. i searched around and found that i need an adapter for the onstar. my question is do i really need this? i dont care about onstar at all. these adapters are really expensive, is there a short cut around this?

i installed a hard drive radio in my sisters tahoe...the second harness has one wire that seems to be the "remote" wire for the factory amp. I just ran the remote wire from the radio and tested each wire( on the second harness) until the sound came on and just tap it.

so is the factory amp not getting power? if so how much power does it need?

it just needs the remote wire like a aftermarket amp. its powered up through the batter but needs the remote trigger to know when to turn on and off.

any idea which one this would be, on my jensen its blue, perhaps same colors? btw thanks for the help

haha man i read this post to late. it is the pink wire, but i was lucky and that was the first one i tried and it worked like a charm. why was this info soooo hard to fine i googled for hours and hours and all i could find where these super expensive adapters. i guess everyone wants their onstar.
