I am currently going the step forward and removing both circuit boards that complete the connection process.
I opened up the body of the guitar, and then the neck. You'll find a circuit board similar to that found on the neck for the body.
I just cut the circuit boards off, after tracing the leads in the circuitry to match up which wire goes to which and then marked accordingly.
So then I just stripped each wire after pulling them apart from the ribbon form to make it easier, and soldered and taped them off. I ran into a successful ending, except I have lost response for the blue and yellow buttons, which I am going to work on later when I have time. But yeah, this also works if you want to just make sure it is a no-fail direct connection from button to wireless transmitter.
I think that the whole detachable neck thing is personally a bad idea. It's not like people will necessarily do it, I could see if the guitar was much bigger, then it would need that option possibly, but with a small guitar, I think it was a rushed end-development decision that needed to be thought through a lot more.
But yeah I might post pictures of the end result once I figure out why two of the eight wires aren't fully going through.
