Hi,
About the same time I was digging my Sangsetia out for re-wiring and pulled my JJC board out. Actually I had 2 Electronize esc's fail weirdly and I hoped to goodness the JJC unit survived, and it did! The OP was asking about connections -I didn't remember myself at the time but hope this helps because mine is a turbo caterpillar unit and I've never heard anything even close to a marine caterpillar ever since (for a sound unit), save for standing next to one...
- red/ black -power (no terminals on mine so must have been pre-wired tails as the heat-shrink on the PCB is still intact)
- terminals between the power leads -speaker (8ohm from memory)
- orange red black triplet -throttle from receiver (needs no explanation)
- audio lead with 3.5mm jack, from memory, output to an amplifier
- 2 blue pots on the board, adjust the sound, can't remember -probably idle and how "lumpy" it sounds
I can't find the original thread on searches so hope this pic helps! I had three of these back in the day, first one self destructed on power-up (mission impossible style) and was replaced FOC as a fault, this replacement probably what I have, third one I sold and regretted ever since.
...Voltage I cannot remember but seems independent of throttle, I'm guessing up to 12.0V. Mine seems fine on 7.2 or 8.4v.
Hope this helps, just sorry I can't find the exact thread since.
