1970 combo gauge wiring Options

[Cfletch]

Looking for some specific help here regarding a 1970 Combo gauge and wiring.

Basically I need to install my new combo gauge that has 3 separate gauges in for fuel, oil temp and oil pressure. I had John Bell make this gauge for me. I can't find a good wiring diagram that will show me colors of wires and where they belong on the back of even a normal combo gauge for that era and I am a little stuck.

Gauge has the above, but also the original normal stuff such as brake, alternator, oil pressure light and all of that. Can someone point me ideally a color coded wiring diagram specifically for the gauges so I can connect up the normal stock stuff and then worry about the new stuff such as oil temp and pressure?

I just did this yesterday so feel free to reach out directly.

Green/Red - factory idiot light for oil pressure (already run to gauge)
Green/Black - Oil temp (should exist on passenger side harness near battery tray, will terminate before shifter unless you have the appearance package and it goes to center console)

Those are the factory 914 colors which should already exist in your car. You will want to add/run an additional wire for the oil pressure number gauge as the factory harness never included one.
