Golden Harvest v3 Phase 4 - Wiring Check (RGBW - In Hilt)

[atodd]

I am upgrading a cheap Ali Express saber (Kanan Jarrus) so I can install his font, among others. The current chassis has a board similar to LGT but isn't. Above that is a switch/USB-C PSB board that the RGBW connects to. I want to KEEP the switch/USB-C PCB if at all possible. I just want to make sure I translate everything over correctly. There are a few pads on the current board that I don't know what they are. Also, I have a lighted momentary switch and I'm not sure if I connect the LED to one of the high powered pads or an accent pad. I've labeled everything I can see and connected everything that is obvious. Sorry for the mess of a diagram. I wanted to get both boards on the same page to get a better visual. So, here are my questions:

1. What are pads P and B+ on the current switch PCB?
2. Of the six pads that connect the PCB and current board, what are VBAT, LED, KEY, and 5V?
   Best guesses: VBAT (no idea), LED (switch LED positive?), KEY (something to do with the USB), 5V (not sure).
3. What do I connect D+ and D- to out of those six pads for the USB port to work?
4. How do I wire the switch LED?

Ok. First, why are you trying to repurpose that usb/switch PCB rather than using a new switch and a seedling that are known compatible with the GHv3? Second, I would need to reverse engineer the traces on the PCB to know for sure what the pads you are asking about lead to, but there is no guarantee that it would be compatible with the GHv3 wiring. And three, why do you have the speaker wired to both the original sound board and the GHv3?

I am wanting to repurpose in order to save money, and also because the saber it cut to fit the switch and USB port. So, if I purchase something different, I feel like it would be too much work to get the new switch and USB port positioned correctly. AND, it is USB-C, which I don't have to have, but the saber is cut for it.

I can take a picture of the boards if that would help. I understand it may not be compatible, but wanted to give it a shot.

I show the speaker wired that way just to show simply where they go. The diagram is not a representation of the final product. Sorry for the confusion!

hmm... well I can look over the PCB but I would need high quality clear shots of both top and bottom of the PCB to follow the traces. Can't really promise anything though.

I understand. Thank you so much. I will get pictures asap. Here is an updated graphic.

Here is an image of the bottom side. The top will be hard to get but I will if needed.
