I recently installed a 2 in one switcher in my Sky Shark game/cabinet
to be able to switch between a 60 in 1 Jamma PCB board
and my Sky Shark game.
I hooked up my existing harness to the switcher and installed the 60in1 board
in one slot and bought this harness extender :
http://www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&item=230656177024&ssPageName=ADME:L:OC:US:1123

to install in the other slot which will attach to my Sky Shark PCB board, but

I only get a blank screen on the Sky shark game now.
I know the harness extender is good (switched it with the 60in 1)
but notice that is has many more wires than my existing harness
had. Do I have to go through and "remove" wires to match my exising harness
that I had to the Sky shark game, or did I buy the wrong Harness extender?

thanks for any help you can provide,
mike

is this the jammaboards.com harness? Those have substandard wiring which doesn't let the current flow like it should because the wiring is too small. This may cause issues on some games that are touchy about voltage. Did you try turning the voltage up on the power supply? I would try that first and see if that makes a difference. There should be a knob on the power supply.
 
I don't think this came from jammaboards.com -
bought it on Ebay from Hollandcomputers ID (in Northeast Ohio)
Jammaboards.com is located in N.J.

It looked to me to be a quality harness extender.
I guess I can try to turn the voltage up, but
the 60to1 board works fine when attached to this harness.
