If you're using a 551A or B "shoebox" KSU, then only slot 4 has AG and AB on pins 3 and 18 of the card edge. The other slots have this wiring rolled up in a sleeve between the hinge and the 66 block. If you choose to cut this open, be assured that you'll regret it. I'd just cut any wire-wrapped leads from pins 3 & 18 and strap those pins together with slot 4. Other KSUs, like ITT's have these pins brought out to the 66 block labeled simply 3 and 18 on the block's fanning strip for each slot.
