Grumpy About your stop light circuit. Let's say it starts at the front stop Sw. power comes in as a black wire then turns into a green/yellow wire from there it goes into the headlight bucket to a five or six pin connector comes out of the bucket goes in the main harness. Then out the harness at the rear of the fuel tank. Then it goes two places one is the rear stop Sw. and the other is on top of the rear fender under the seat. there is a bullet connector there with a few others it is still a green/yellow wire or in your case it should be
From there it goes to one more and the last bullet at the stop light.
Is this the information you are looking for??
Have not heard back from you. did you figure it out?
