What is ‘VCC’ on my controller

Hey guys, I posted here yesterday about testing a throttle. I now have an update. I plugged the throttle into my known working controller and the throttle does in fact work.

Anyway, I now have a new question. I decided to pull apart the controller that didn’t work to see if there were any markings for a power switch or key. There was nothing immediately obvious however, I did find that there was 1 plug that had a wire going to the positive input and another going to ‘vcc’ then there were two other plugs that had one wire on each going to ‘vcc’ as well as both having another wire going to the batteries input ground wire.

Would these be anything that would enable the controller to power up? I will attach photos of what I mean as I’m not sure how well I explained it. Thanks

The plugs

Where some of the wires go. Note p+ and p- for main battery power inputs

where the rest of the wires go to ‘VCC’
