Ok so the guy who I bought my 97 brighton from did all sorts of crazy shit i hate to it, and one of those things was taking out the plastic piece u can attach wiring harnesses to for decks. So now there's a bunch of random wires in there and SOA want's 35 bucks for there friggin subscription to their manuals. Does anyone know where I can get wire codes for my car or should I just have this done by a pro.
