option codes- can someone tell me what they mean?
 

I was reading the sticker on the underside of the trunk, and I noticed the list of options my car was ordered with. I was curious what they mean and hoping someone could tell me what each code refers to. Here they are. Thanks.

C02
158
454
490
494
650

Troy, I can 'decode' most of them:

158 relates to the radio but it meant different models in different years - 'Monterey' in '86 & 'Reno' in '87. Don't know the model for '89.

454 is cruise control

490 is HiFi sound system (?)

494 is two speakers on rear shelf

650 is electric sunroof

Don't know about C02 I'm afraid.

'69 911E--------->R

C02 is catalytic converter.

Here's an option decoder:
