I have a GIpro. It has a rectangular connector. It fits on the white connector in the center of the picture.
Thanks for trying to help.
I'm starting to think the GIPro have at least two versions of their gear indicator product ("ATRE").
Because the instructions in the box clearly say "Look for a pink/blue/black-white connector".
It is hard to see the exact shape of your connector, but the one I have on my bike is more of a 2x2 square.
If I'm not mistaken the pink wire is the one that carries the voltage signal of the current gear.
I read your other posts on this subject in this forum, and never understood why GIPro need to connect to the dealer mode connector. Maybe they started that way and moved to a much simpler (and cheaper) design?
They only need to need to manipulate (read and modify) the voltage on the pink wire to get all their functions working. Really no need to have any complex ECU communication for that.
The ECU just gets a different "fake 4th gear" voltage level for the ATRE.
This thread (very old! from 2006) clearly shows a triangular connector on the left side:
My connector has the same wires but looks much different -it is 2X2, one 'port' is unused and has a black filling.
