I got my org cluster out of my '68 144. Been looking at the plugs that were connected. There are three half circle plugs with 4 pins and one straight one with 2 pins.

I have a Haynes manual that shows the plugs and wire colors but it doesn't seem to show where the wires go from the plugs. The bigger diagram is very fine print. Need to find a magnafine glass.

Wonder if anyone else has done the GT swap or has a better wiring diagram. I need to know which connector going to the cluster would carry the OD light wire? My wire might be missing from the plug as my car I assume has a BW35 auto wiring harness.

Also, the GT cluster has two push on leads for the rotating switch that dims the cluster. The rotating switch has three leads. One appear to go to ground on the cluster plate. The org cluster must have powered this via one of the connectors. Appears I will need to run wires to this rotating switch. Or maybe those leads were outputs to other dimmed lighted objects on the dash.

And last, the tach has one lead open. Assume I need to run a wire from there to neg side of coil.
