Thanks for all of the replies!

Car: 72 challenger, no power locks, no dome light timer.

This bulb is apparently a direct fit for my original 1004 bulb, the locking posts and bulb pins align with the old bulb.

The pins on the LED do not have continuity with the bulb base, at least what i can measure.


I haven't had a chance to get back in the car to measure anything else just yet.
