G-body (or GM) wiring help needed...

[SRD Art]

I'm swapping an '84 Buick Regal steering column into my '79 Cutlass. All the plug terminals transfer over except the extra plug in the '84 column photo below. This extra plug is on the gear selector switch located lowest on the column.

The plug that is common to both is the one with the green and blue wire. This turns on the reverse lights when the shifter is put into reverse. The extra plug (with an orange wire with a black stripe and a black wire with a white stripe) appears to be associated with when the shifter is in park.

Can anyone help me identify what the extra plug is for? Thanks!!!



Here's my original. I thought of swapping the switches but they mount differently and that won't work.
