While installing the dual plug coils today (thanks, Rick! (Motorrad Electrik)), I came across this blue connector in the OE harness:
Any idea what accessory it is for? The bike is a 1988 R100RT. The schematic in Haynes identifies it as a "Connection For Special Equipment," but doesn't say what special equipment. It's not for the 4-way flashers or heated grips, as these have already been installed using different connectors. The wires tie in at several points to the lighting system -- maybe a connector for the flip-out driving lights that were an alternative to air ducts in the RT fairing nose?
