LED taillights and how to wire turn signals

[roughrider]

After long searching for help, I suspect there is a smart person out there. I have 2 LED tail lamps from from Mac's (with a black wire: parking lamp and a green wire:for Stop and Turn signals). The old turn signal unit is an old one model 9000-ST which does not have a separate wire for Stop lamps. It does have a wire for Left turn and a wire for Right turn hookup to those lamps.
I would like to use the brightest part of the lamp (green wire) for both turn and stop functions.
How do I wire up those rear lamps so when wiring is tied together for Stop lights, the Turn signal function doesn't cross over to the other side and make both rear lamps blink? Thanks- roughrider in NM
