PSOne MM3 wiring diagram?

Could someone please point me in the direction of a wiring diagram for the MM3 modchip, going into an NTSC(U) PSOne console SCPH-101. I've googled around with no luck, only diagrams I can find are for the 102 revision.

 

There is no PAL or USA pictures. PSone is PSone

 

Hey thanks for that - and board revision is not an issue?

 

There are 2 board revisions, with slight differences in the install.

but its 2 versions worldwide iirc, so just find the 2 pictures and look at which matches (chip locations) and use that
