guys, i need some help with the monitor wiring: my cabinet had an electrohome go7cbo monitor installed, but the original frogger cabinet used different monitors. therefore, the monitor connector of the harness doesn't fit into the go7cbo connector on the chassis. normally not a problem, just switch the connector, but i don't know which wire is for ground, for vertical and for horizontal output.
here's a picture of the connector:

rgb is clear and i thought that black would be ground, but what about yellow and white? additionally, there are schematics which show black as
not being ground (check out schematics 700-0068 vs 700-0069).
here is a link to the frogger manual!
would be cool if you guys could help me out here ...
