Hi everyone, Looks like I arrived late to this thread. I saw the video posting for "TK11778's HOW TO: Super clean helmet electronics/interior build." Using the video and photos as a guide, I did a simple wiring diagram attached below. For the (amplifier / AKOR battery), I cut open the shrink wrap sleeve on the unit and spliced the red wire to a remote switch. I don't know where that 'AA' battery (in the red circle) with the green bottom in the photo below powers. Does anyone in here know what its used for and what it provides power to? As for the wiring diagram, does it look correct? Since I am not electrically inclined, I would like to reach out to this group to see if anyone could shed some light into my build. So far I have the voice modulation system as well as the external audio headphones and 4 fans from Henry. Any information would be greatly appreciated, thank you.
