69 camaro courtesy lights
 

how did the package work did it recived a under hood and trunk light when you had the lower dash lights

IIRC, the courtesy light in the roof was a stand alone standard install on a coupe, and under dash for convertibles. After that, ZJ9 was an upgrade.

Four variations, different pricing.

The trunk and underhood light were only available as part of the ZJ9 Auxiliary Lighting package, which had to be ordered separately - it wasn't included in any other option.
Doc

so the car could have just the lower courtesy dash lights alone my car has standard interior but has the lower courtesy and glove box light only

No, probably added via the accessory catalog.

All the lighting via ZJ7 would listed for $13.70.
