Mapping the connections on the board
The board is screwed in with two Philips head screws and tips out along the bottom edge. We disconnected and cut the wires leading to TJ's various parts. Below is a photo of the board with its original wires, most of which are clearly labeled.
The wires are listed by pin number in the table below.
