I have two pairs of controlled lamps that say one thing and mean another. I think someone along the way replaced a wiring harness that ended up being backward or at least scrambled. When my EBC wants to light HIGH SCORE it instead lights BALL IN PLAY and vice versa. It also swaps TILT and GAME OVER. I have several options to fix the problem and wonder if anyone might have a suggestion. Swap positions of lamps, swap positions of female molex connectors in a harness, or swap wires and leave lamps where they are. There are other solutions, like hacking a couple of 2x6 molex connectors to fix the problem.
There are two reasons I ask for your opinion. First, the wire codes on the board and the flashers match; the disconnect is in a cable that has molex connectors on each end (one end picks up some wires from another connector, so simple replacement is not easy). Second, the swaps that need to happen are both on complete opposite sides of the backglass. Swapping wires or sockets might not be so easy and then wire codes will be ambiguous for future troubleshooters.
