 I am now putting in Dynamat and a new carpet kit, and in doing so noticed a set of wires that I had not connected because they were kind of hidden under the tunnel carpet. They are the four wires that go to the hand brake.

What do they actually do? I assume when you engage the hand brake a light on the dash lights up? I had never noticed before (I have had a JH since 1979!). I see the middle light that lights up when the brake pressure differential valve goes bad also says PARK, so probably that. Maybe this switch often goes bad?

Does anybody know the order that the four wires should connect? The wiring diagram is confusing and the handbrake switch seems to be mixed up with seatbelt switches. The actual switch at the handbrake is 2-two connector blocks, and the available wires are Black, Green, Black/White, Light Green/Red(maybe orange).

If nobody knows, I'll start trying all 24 possible combinations
