Why is there a GRND connection on my 65 ignition switch?

The FSM does not show one and I can't think of any reason to need one.

Possibly for the key buzzer? Just a thought....

You only are using 5 terminals and not the one that says ground right? Typically the ones that had the ground used was for a bulb test for the warning light in the cluster as I recall. C-body cars.

Who knows what switch is in my 57 year old car! Hell, I'm running all the connections to ground. I have a Infinity system. All switches go to ground to operate. Pretty neat system.

Never heard of an Infinity system. Whats that?

It is quite sophisticated in operation but rather simple in theory. As mopar 3 B stated above, all switches use grounding of the battery feed connection to signal the Master cell that the operator wants to use whatever device the switch controls. Since very small current is required to operate the computer, very small wire size is used (a weight saving feature) for signaling. The Master then sends a signal to an individual node in a Power cell which does the work of sending operating current to the device desired. Each cell includes diagnostic LEDs, fuses, and 25 amp load capacity. Cell connectors come prewired with top quality cable. A CAN system connects the Master to each Power cell, which are supplied with fused battery power to supply all devices. The use of the CAN system eliminates large amounts of wire which also cuts weight and routing difficulties. It takes a while to wrap your head around the wiring (at least it did for me) but, it is an impressive system. Of course, they have a web site you can access.

All switches go to ground.

So basically it is an integrated power module with load relays and communication ability.

I didn't wire it but that's a possibility.
