Tighten it to the dash so it gets a better ground, add a 631 bulb (or LED equivalent like I did!) And it should illuminate whenever the driver or passenger door is opened.

boy, that makes me feel dumb haha. thank you.
The only stupid question is the one not asked, besides, now you know! They were completely missing on my dad's convertible. I didn't even know they existed at all until I got my '66. Only noticed when I put in a new under dash wiring harness in his car.
