Alright Im trying to see if I have the pins in the right place which it looks like I do but then I realized that pin 2 which has ground looks different than the rest and I didn't plug it in, now I know this might sound stupid (bear with me its my first real arcade experience since my other arcade is a mame). Now everything looks fine except for that one which looks like this http://imgur.com/w4lEz2U,zoElbXQ,awQEUcW,dm2cFt4#0 the one im talking about is the black one. So where am i supposed to connect this one? also im waiting for the meter to finally get here, bought one online thanks to you guys 

Hello friends, I wanted to know if somebody can help me out with this board. So I am i'm fairly new to the arcade scene and last year I bought a cabinet with a 60 in board, after a while I bought a 412 in 1 board, which I swapped for the 60 in 1 that I had, now when I swapped I noticed that I wasn't able to coin up or pretty much do anything it displayed the menu and everything else but I couldn't coin up or anything, so when I looked at my jamma harness I noticed that the previous owner of this cab had cut a bunch of cables and had somehow jerry rigged the cables so the board could work, but then I noticed that some of the cables that were needed for the 412 in 1 board were not there or they were just cut, so I bought a wired jamma harness from jammaboards.com and plugged everything back,   and there is nothing on the screen. I am using a pc power supply just like when I had the 60 in 1. Here is a pic of the jamma board wire map and the wire map that came with the harness. If anyone can help a noob out it will be greatly appreciatedhttp://i.imgur.com/lNnllmk.jpg.

TL;DR Bought a new jamma harness because the last one had cables cut and some missing so when I plugged the 412 in 1 with the old harness it displayed everything but I couldn't coin up or move because it was missing some of the wires in the harness, then when I put the new harness  nothing shows up.
