how is the door adjar switch wired on a 71

ok, I see on the passenger side it has three wires, that are attached to small clips that go thru the plastic ring and I guess when the switch is depressed it makes the contact with the three wires.

"when the switch is depressed " blue- just the opposite. the door ajar switch and courtesy light switches are "open" when they are depressed with the door closed on them. When the door opens, the internal spring on the little plunger expands and closes the switch, makes contact and completes the circuit (which for these two switches is the ground circuit).

Going from memory, but I'll add that I think one of the wires (white?) is for the door ajar and the other (blue?) is for the alarm system. Black is ground.

I replaced my door ajar switch last summer. It's helpful to know there is a small access panel in the rear well wheel. Remove the rear wheel and pull the panel and you get some access that I found helpful.

thanks to all, I replace all 3 wire tabs as there was only 1 there and now the switch works.

Door Ajar switches are not part of the factory alarm system. They are door ajar only.

Alarm system uses the front door jamb switches.

My door ajar switches (the ones at the back of the door) have a white, black and blue wire. Per the wiring diagram, the black is ground and the light blue goes to the door ajar warning light. I thought the white wire was for the alarm system. This is a '72.

mine is a 71 and I have the same 3 wires, didn't trace them but it works!

Check the AIM for your model year. Some model years do not have the ground on the passenger's side, others do.
