Hey Captain,.... I can only find a diagram with no "year model" listed, but here goes....
The connector you have identified has a black wire (and a green yellow I think). Check it for any changes when setting/releasing the park brake, to see if it gains and/or loses ground. Simply continuity test to battery ground. if it doesn't show any continuity, the park brake switch may be broken (do the test with connector inplace). Using the same jumper wiring you should have created for testing, Ground that black wire and see if your troubles go away. Use ground to battery, not to vehicle chassis. If it does show continuity with no change, you'll need to disconnect the black wire to eliminate the park brake. I can't tell from this silly diagram, if the black wire is a common between the clutch and park switches.... Kinda crappy diagram.
This diagram I have found is poorly keyed, so I can't tell whether the switch is "normally open" or "normally closed" otherwise I'd be more decisive in diagnostics...
Hope this helps.
