New Indicator Lights

Postby Hutch1 » Tue Sep 18, 2018 2:53 pm

I'm working through the wiring on my 1982 CB650SC adding new gauges and indicator lights. The new indicator lights (2 wire) are wired red/+ and black/- ground. I'd like to add these to the 9 pin OEM connector in the same locations as the OEM wires. The OEM wires are as follows:

light green/red - neutral lamp circuit originating from switch
blue/red - oil pressure lamp circuit originating from switch
black/brown - neutral lamp oil pressure lamp from fuse (hot)

How should I wire the new indicator lights? Seems the black/brown wire should go to each of the red wires on the indicator lights, and the circuit wires (light green/red & blue/red) to black ground on the new lights?

Well, I have it sorted based on a response from the SOHC4 forum. As I guessed, and it was a guess, the */red circuit wires from the switches act as ground. Attached is an image of the new gauge cluster. I also moved the ignition switch held in place with a set screw. Also filled in the fork air assist holes since the air assist was useless IMO.
