Convert MAME cabinet to JAMMA so I can use arcade PCBs and also MAME PC?

[sofakng]

I've built an arcade cabinet many years ago using arcade parts (Happ Controls buttons, trackball, etc). 

Display - 15 kHz TV with component input
Video - DB15 VGA to Component (YPbPr) transcoder (Crescendo TC1600)
Controls - I-PAC and OptiPAC with arcade buttons/trackball
Audio - Two-channel stereo amplifier connected to PC

Everything is currently wired into a dedicated MAME PC, but I'd like to start connecting arcade PCBs starting with a Neo Geo MVS MV-1C.

Can I re-write everything in the cabinet to a JAMMA harness?  Are there any guides on how to do this?  I see the JAMMA pinout and can write the buttons pretty easy but I'm not sure how to do the video, etc.
I'd like to be able to unplug the JAMMA harness from the MAME cabinet and directly connect an arcade PCB and then return to MAME, etc.

Can anybody give me any advice or information?

Rewire you cab with a JAMMA harness. Make sure it is not a Pandoraish CHAMMA harness.

Then read about this.

That will be a good start.

Thanks so much.

Can you recommend a quality JAMMA harness that I can purchase?
