Adding some pictures for those using my cables.
I’ll add monitor cable pictures later.
These show programming with supplied 23p plug, plus adding a program port to original Gem plug.
T3 & T4 will also need connect monitor cable to p2 & p17.

From memory, subject to correction:
To trouble shoot and monitor voltage and current, select “monitor” after disconnecting pin 17 & 2.
You will then be prompted to turn on key.
Re-connect 17 & 2. Follow prompts.
Monitor will then display all switch positions, sensors, F1 amps (forward), F2 amps (reverse), A amps.
Select functions to graph. Such as F versus A versus B+.
