I have an 88 Firebird 350 Formula TPI and when i bought it there was some stupid audiovox silent alarm on it where if you activate it you cant start your car. I unplugged the battery and the alarm went off and now i cant start my car. I cut everything from the alarm out and i saw that the only thing that needed to be re connected was a thick yellow wire. I did that and still i get nothing no light or anything. I noticed in the back left of the driverside by the gas petals there was a little harness with a yellow and purple wire that wasnt plugged into anything. IS that whats preventing my bird from starting and if so where does it plug into? I really appreciate all the help in advance
