Model 3 pins (transcribed from old printouts)

Hi all,

as I was going through my VF stuff and getting the VF3TB board up and running I ran across of all the documentation that Kbcat had compiled when making his own harness. This might be of interest to anyone with the boards so I figured I would post it here.

What follows is the text as I found it. I typed it up exactly as I saw it, I added nothing nor took anything away and the original document wasn't mine. Something goes badly while using the below information please swear at someone else.

This is great, thanks! curious if pin 12 and 20 are supposed to be evade?

 

I'm sure they are. I spent too long just playing on my TB tonight when I could have been checking the pins for accuracy.

 

Thanks GodEater!

so I stripped the first wire which I think is supposed to be coin in, tied it to the business end of a seimitsu I had laying around, but I can't seem to activate it. do the buttons need ground, and if so, from where?
