Ignition switch help please

[kens65fb]

Currently my keyed ignition switch is located on the crap steering column installed by previous owner.
The old ignition switch is still mounted to the instrument bezel, but no wires are connected.
I want to go back to the ignition switch on the dash, not on the steering column.

Here is a pic of the back of the switch, I see where the battery wire is connected, where the ground is connected, and where the ignition wire is connected, and the accessory wire connects to the switch.

My question is what wire goes to the top most terminal, looks like "SOL" imprinted underneath the connector ??
