I am looking at the power window/ power lock wire harness coming out of the drivers side door on my 72 GS and there are some pigtails I can't ID. I took them out years ago and now am tring to reassemble them. The small round one with 1 yellow and 1 orange wire ends just inside the body under the dash. There is one on each door harness. The larger rectangular plug has 2 yellow crimped to one spade, 2 orange crimped to one spade, and a larger orange with 2 black stripes. They are wrapped to a larger orange power feed that plugs into the fuse box jumper that powers the seat, locks, and windows. The only thing I can think they might be for is power seat back releases which this car does not have. I have never seen a car with that option.
the connector in the second pic is used for the power seat back release. which plugs into the door jamb switches for that option. the connector in the first picture is for the the power locks and plugs into the harness that runs over to the pass. side. then the single lead plugs into the fuse block jumper harness thats on the "constant hot " (which means it has power all the time regardless of key position)conector in the fuse block hope this helps rick
Thanks for the input Rick. It makes sense that the smaller connectors go to door jamb switches. That is right were they reach. I do remember seeing cars with 2 switches in the door jambs but never knew what the second one was for. There is a punch mark just below the dome light switch where the hole would be drilled. They must have packaged those wires with the power window/door lock harness in an early attempt to commonize or simplify the assembly process. I don't think the larger connector goes to the other side. There are already 2 runs of wire from the left door that run across the dash to the right side and match up to the harnesses coming out of the right door. I'm guessing there would be another short harness from that connector to the seats. I'll check the wires from the small connectors with a meter to see if they run to the larger connector.
I imagine a wiring diagram would help . I might be able to assist there . Also I have a set of seat back releases and am thinking that this is what the wires are for . I can check to see the color of the wires on the releases but this is not aways the same after a connector . Sorry Steve when I read your PM I was thinking about the PW and PL wires only . The seat releases I thought were connected into the lock harness . I will look up a pontiac and olds set up to see what I can find John
Rick w. just replaced the complete wiring harnesses-- two with pw and one with power door locks -- on two 70 GS cars for me. We used M & H remade from the factory blueprints. They work as new.
I've heard nothing but good reviews about the M&H harnesses. I've been talking to Darrin at M&H and sent him the same photo's. He's checking into it also. In my reference materials, I didn't see that these seat back locks were available in a 72 A body. Does anyone know if they were? Did it replace the button in the middle of the seat back? Steve
Mystery solved. I found the harness PN tag on the wire up in the door jamb boot. 9814453. Parts book calls it front door lock and seat back lock harness. I checked it with an ohm meter and all the yellows were connected, all oranges were connnected and the large orange power feed from the fuse box powered up both the door locks and fed power to the large connector to go to the seat back harness if so equipped. Thanks to all for the feedback.
Steve , I got my seat back releases from a Pontiac A body . If you get a harness without that wiring I might be interested . I plan on adding it to terrys car along with a power seat I found . I added P/L , P/W, CRUISE,R DEFROST,P/TRUNK last year
