.100 and .156 for the solenoid driver board
.100 for the mpu board and lamp driver board
.093 for the display connector harness and power supply

The 093 are pretty robust and would be the last I'd replace. .100 I would replace both the male (board) and female (connector) connections. .156 I inspect closely and if tarnished/plating gone I replace both as well if not just the female connector side.

Practice on scrap wire a bit first to make sure you're making good crimps. The ratcheting both wire and insulation at same time works the best IMO.

Quoted from Nokoro:

I can't find the start button in that switch matrix, though.

It's on the cabinet wiring page you'd have to overlay it. It's ST0 I5 (column 0 row 5)

Quoted from Nokoro:

Interesting. Is it technically part of the switch matrix at that position, just with different wiring and going to a different connector?

Yes, it's still part of the switch matrix. Some strobes are shared between 2 different connectors j2, j3. Why bally chose to not draw the complete matrix on one page I'll never know. Stern did the same thing, but at least they include a page that has the switch matrix drawn the same way for the cabinet as the playfield switches.
