Here is a picture I drew of the second board and what the connections are supposed to be. I think it makes it easier to understand what goes where.
Before getting started remove both grips from the sides. Then unscrew the LCD board which is on top. Gently pull the board up to remove it.
In this Image you can see the actual second Board as you can see (or not) I used a paperclip to use as a jumper from the 1st to 3rd inlet.
This is the Eye Board and what you need to take out. It has 4 connections on it. One comes directly from the eye and the other connections lead to the second board and relay the trigger and battery connections. Be careful when removing these.
