Thanks for clearing that up. I have another two questions now:
1. Did the blue plug change position after the LCI or why did you mention that? Because there's two versions it seems, one where the blue plug is left and the other where it is right.
2. In regards to your .txt file, PIN 3, 4, 6 are connected directly to your Teensy, right? POWER switch, LED and DSC Switch.
1. Yes the Blue and Black connectors on the JBE are flipped on older models. I believe pre-JBE2.
The notes in that text file were made with an LCI M3 as the subject. It had a JBE3.
2. Yes, that's correct. The teensy drives those LEDs and contacts directly as it is in charge of those functions.
