'My' Jeep, which is like his 'Wrangler' only has 'one' bulb and 'one'
filament for brakes and signals which requires a logic circuit to
separate/consolidate the signals.

You seem to be 'full' of good advice (not).

There is no brake light wire.

Have you ever seen a Wrangler or CJ before? There's only one bulb on
each side for the stop, turn, and running light functions.

Nope, there's one wire for the brake/turn signal, and one wire for the
running lights.

Doesn't exist. Hence my need for some kind of logic circuit, and my
amateur attempt to design one myself.

You think? :)

Anyway, I went and ordered the JC Whitney logic circuit, which should do
the trick.

Nope, my Wrangler is a '93, and like all light trucks in the US, the
CHMSL wasn't implemented in Wranglers until '94.
