This is a continuation from this page which covers a schematic produced for Greg Marsh who makes his own harnesses for Norton Commandos in a very specific way.

This time round, Greg is working on a 1975 MK3.

You can follow his project over on his site by clicking here.

Greg reached out and asked if I could produce an iteration on the Pre-MK3 wiring diagram he uses to cover his MK3 project.

Wiring Diagram

Here is the Custom wiring diagram for the MK3 Commando that Greg is working on.
