Griffith 500 instrument wiring

[griffert]

Im rebuilding a griff 500, 1994, serpentine , and bought a replacement dash and gauges - I now have a problem with wiring connectors that don't match - does anyone have any detailed info or wiring diagram I could copy for the speedo/rev counter area ?.
Cheers

I drew my own diagram for a 96 Griff 500. Will this help?

Rev counter is 3 wires: ignition switched +12 (green), GND (black) and signal (white with black trace)

Speedo has about 6 wires and goes to the little black box thing. This includes the oil and charging warning lamps in the speedo. Not sure on all the colours.

Thanks for the reply, I'll check the colours out tonight and see how mine match up, any info on signal voltage + current readings would be appreciated so I can check the readings out.
