OnStarHelp

I think the issue is that there is a wire jumping from the stock head unit harness to the on star remote harness. I am not the best with schematics but I think if I wire up the harnesses again it would still continue to do the horn until connecting the two wires that wouldve been connected with the jumper. If anyone has the head unit and feels bored sometime maybe they could see what the harnesses look like and take a picture for me. I know it is a long shot and people are probably commenting on what they remember their experiences messing with the head unit and onstar, etc Thanks for all responses

Hey guys, I am seeking some help on the wiring of my 2003 Outback with the 6 cylinder 3.0 L engine. Several months ago I was tryign to install an amp and made the mistake of clipping the 2 harnesses for the stock radio and outdated On Star system...big mistake. Since doing so the anti theft mode has been engaged with blinking lights and horn blowing. I am 99% sure that the problem is with a wire that jumped from one harness to the other, but at the time of working on it I didnt have the battery hooked up and dicovered the problem later. This has left me with a poor recall of what was going on and I really would appreciate any help seeing how there aren't many places that will even rip me off over this issue. It seems most shops wont go behind soemone that has already started screwing things up. Thanks in advance for any help to solve the problem.
