Repinning the GI connector: the yellow wire loop through the keyed position
On the original insulation-displacement GI connector, a yellow wire is punched down in two places so it loops through: it feeds the playfield and backbox GI and continues on to the coin door lamps. One of those two positions is keyed and has no pin on the board header. When replacing the burnt connector with a crimp-style one, splice the two yellow wires together (under heat-shrink), crimp the joined wire into the live position only, and put a key in the dead position as before so the plug can't go on wrong.
