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.

on my 164 the OD light was not connected to the master plug so when I installed
the OD, I just ran a wire to it from the OD.

Will have to look at GT cluster closer see if I can spot a separate connection point on the GT cluster for the OD light.

Want to clean up the contacts as well as where the light sockets meet the circuit board. Bit of oxidation there. Wonder what would be best to do that.

I just followed the wiring from the overdrive warning light on the cluster to the connection pin, then matched up the connection points and found which wire is the OD wire. Cannot remember color.
