I have no owners manual,learning about our 88 911 on internet.I have had car running as posted last week. Need help. We have no radio,interior lights,fuses look ok. I installed new battery ,everything else works i.e. lights ,heater fans etc. Also suggestions on updating A/C R-12 pump or ???? find outlaw r-12 guy.Read some posts about belts,at 20k miles both look original,look ok also. Which manufacter to use? Thanks from snowy MT. I'll try to get a photo!
