This kit is designed to mount two large rectangular Bosch lights on two arms clamped around the fork legs at the lower triple clamps of a K100, As such the lights cannot be mounted in this fashion to an RS/RT/S as the bodywork is in the way. On my 1985 RS, the lights were mounted utilising the engine protection bars. The electrical connection was a 'plug & play' operation.
However, I've struck an electrical road block in fitting the kit to my 1992 RS. The bikes electrics have a white female 4 wire plug (green, red, black and grey - I think). However, the wiring harness for the Light Kit also has a female plug, albeit a 7 point black one. But although it also has 4 wires attached, the colours are brown, yellow, white and red/yellow.
My plan is to make up four wires to connect the two plugs. Using a test lamp will establish the power source, then switching to an LED will identify positive and negative. But that's the limit of my auto electrical knowledge.
How can I establish which colour wire from the bike connects with which colour on the wiring harness?
