Wiring 3rd brake light

[Greatisland]

Hey guys,
I picked up an alucab for my 2024 Tacoma off-road premium.
I wired in the 3rd brake light to the left hand side tail light. It operates great when I brake, but when I signal left the rear brake light also flashes. From the looks of it I need to tap a wire before the turn signal signal goes out. Does anyone know a better location to tap into?
I looked at using the trailer wiring but ran into the same issue.
Thanks!

Were you able to come up with a solution?

I Ordered this and will update if it works. Hope it is that easy!
Not sure where to install this as it needs a signal from each turn signal (left [white wire] and right [different color] - to the 2 yellow wires on the logic module - one each). I believe the logic is if it only gets a signal from one it does not send the signal on to the 3rd brake light (Green wire on the logic module). If it gets a signal from both it sends it to the green wire up to the 3rd brake light.

I had trouble with this on the 3rd brake light for my Softopper. This logic device does appear to be a cheaper solution than I found, but still requires you tap into BOTH taillights. I ended up using this harness from GG Offroad so that I didn't have to break any wire insulation. It also had the advantage of carrying the bed white light signal in the same cable. I used this to add an overhead LED strip on the topper rail.
