I'm trying to wire a MP distributor in a 1966 hemi charger with butchered wiring. I think I've identified all the wires with the exception of the tach feed wire. I have a 1967 service manual that states this wire should be gray with a tracer. However, the wire I have is green with a tracer.

Should I keep looking for a gray wire with tracer or is 1966 a green with tracer?

Thanks!
