Hi, I'm David. I just got a 89 CRX Si that has a broken heater control and a cluster of cut wires...stereo wires. I'm looking for a wiring diagram for this car and a place to buy a new or used heater control panel. I don[t know much about cars but love this one and want to fix it up within my budget. So if you guys know where I can get cheap used parts and cheap new parts I would be very grateful. Let me know if you need more info and I'm sorry I don['t have the knowledge to return.
