couldn't find with forum search.
On an Ender 3 v2 but they're the exact same connector and pinout as the 3DChameleon.
Thinking about running the other currently unused half of the 3dc cable to the mainboard but don't know if that's the best way, or if there's cheap extensions on amazon etc. (couldn't find myself)
In my Ender 3 V2, I used both of our cables... and just ran the extruder cable directly into the electronics and connected it to the extruder connector inside them. That made a nice clean installation. The stock cable, I just removed from the harness.
