Hi! I have an original Neo Geo 2 slot cab and I just picked up a KTM-F 26" Monitor to put in it. The only part I have a question about is the power harness. The original monitor is a WG 19" standard. The power harness for it is a 2-pin with white and black wires. The new monitor has 3 wires. a solid purple, a purple with a line and a solid green. I know that the solid green went to ground in the old cab it came out of (buck hunter or whatever). My question is: which purple wire goes to what black or white wire? Thanks!
