According to the schematic for a K4 bike, there are only 4 wires into the ignition switch.Red,orange,orange and white and brown.At the first connector, red goes to black with a red tracer on the loom.Orange goes to orange, orange with a white tracer goes to orange and white (on the loom),and brown goes to brown.With the ignition switch on, red connects to orange which goes to the terminal block under the air box.Orange with a white tracer connects to brown.In the parking light position, red and brown connect together.The red wire on the switch is fed from F3,and the brown goes straight to the side/parking lights.Hope that’s clear, it’s from the Haynes manual.On the K5 model there are 5 wires.So I suspect it’s a K5 bike,unless it’s had a later loom fitted when the original corroded into the ether.Hope you can understand that.
