I’m trying to figure out my front indicator wiring which has been modified and get it back to standard. The wiring diagrams show three wires at the indicator. For example the left indicator wiring is Orange, Orange and White, Green. The Green is OK I can see the path back to earth through the chassis and head light bolts, then back to the green in the headlight bucket. The indicator light assembly I have and all the ones I have looked at have a single black wire. Which is power to the lamp and the lamp earths through the chassis. Are there lamp assemblies with a three wire connection?
