Taillight mod - All 3 bulbs light up instead of 2

[Coelacanth]

I remember seeing a topic on a taillight wiring mod where all 3 bulbs on each side would light up when braking or signaling, not just 2 as per usual. I can't recall if it was on this forum or 1970chargerregistry.com, but my searches on either, or Google in general, is not pointing me in the right direction. Does anyone remember this mod or did it on their Charger?

My Charger came like that


Sounds like you need a two prong pigtail, piece of wire and some butt connectors

The info I remembered was a description of some wiring changes and possibly different bulbs, too...because brake/signal bulbs have a brighter intensity.

This is typical light action, at 3:25 of the video:
