Noob with a question. Sorry if this has been asked before. I have a jamma harness and I'm
trying to figure it out. There seems to be a discrepancy in the harness. The icade chart for the harness is numbered on both sides and no color codes. I have a copy of jammaboards pinout which has the color codes. on my connector Pin 15 test switch is red and pin R is orange. According to jammaboards pin 15 should be orange and pin R should be red. Is it common to find some of these wires to be switched. Also pin 8 and J are missing wires for the coin counter. Should there be a key at pin 7/H, if so where can I find one to put in so the board does not get installed backwards. I have a couple of scans of the harness just to make sure I have it correct.
