B12 is for the interlock - this is the mechanism that prevents you from pulling the key out unless the car is in park (automatic transmission only). The WHT/RED wire runs to the interlock control unit - a blue box mounted under the driver's seat. You can remove this box, and the WHT/RED wire can be removed from B12, as it isn't used anymore. After the conversion, B12 should run to the CKP - the solid white wire on the 8-pin distributor plug.

CEL 9 is CYP
CEL 16 is Injector System

Double check your wiring. Which chassis are you doing the conversion on?
