Does anyone know where I can access a hardcopy of the GM Standard Parts Catalog? The current version is only distributed to dealers on encrypted CD's or directly online. Even if the version is from ten years ago, it will help me determine the part number for the wire housings I need for the A/C-heater blower switch on my '71 El Camino. So far, all the junkyard pieces are as melted as mine. All of the companies that make repro harnesses won't sell individual connectors, at least the ones I checked. I don't need an entire harness.

When you find one, let me know! I want one too!

I wonder if Detroit Iron could be persuaded to toss it on CD?

I have a GM Parts & Accessory catalog from late 71 when I worked a Chevrolet dealership. That said, I don't think you'll find GM part numbers for the individual connectors, only the harness. If it's just the connectors you need, those may be hard to find unless you can talk someone like Painless to part with them. GM only had replacement harness assemblies. That said, my book has 3 different ones for 71 Chevelles (El Camino is not specified as unique.)

8901718 - 71 Chevelle w/inst. panel gauges
8901717 - 71 Malibu (S.S. package w/front compartment console)(8-cyl)(exc. inst. pnl. gauges)
8907793 - 71 Chevelle (exc. 454, S.S. Package inst. pnl. gauges)

I also have a CD from Detroit Iron for a 67 Chevelle but the parts books on it is only a couple of months newer than the paper copy I salvaged.

Louie, As I said before, go to your local ACDELCO retailer, not the dealer, and ask about catalog #16A-101, that should be the one that you are looking for to get the connectors that your want.

To Leo Paugh;,, thank you. I checked the local Buick dealership in town on just a hunch that they might have a standard parts catalog. They've been there since the 30's or so and they actually had a 1992 version of the standard parts catalog. Not only that but they also had the AC/Delco pigtail catalog you advised me about. The counter guys there were very nice and let me sift through the catalogs. They seemed kinda' happy to see a customer actually come into the parts dept. It was sort of like going back in time when you could walk into an auto parts store and the people who worked there were the same people who worked there last week and last year and even ten years before that.
Oh well, I looked at all the available GM connectors, housings, electrical accessories, etc., and I only found one of the two connectors I need. They list the three-way connector as part no. PT 572. The other connector resembles an 'L' shape and is also a three-way connector. It's no longer available so I'll either have to find a suitable survivor in a junk yard or just do without. Being that this connector is under the dash and not the hood I suppose using the spade terminals covered with heat shrink will work just fine.
Thanks again,
Louie Hammel

Louie, Thanks for posting what you found, it may help someone else. This is the kind of info that some of us need to get our cars finished or back on the road.

Well I must digress from the last post. After checking various sources today I found out that even the AC/Delco pigtail part no. PT572 which was originally GM part no. 12125660 is also no longer available so I suppose the best choice at the moment is to use the spade terminals covered with good quality heat shrink and tagged with the corresponding terminal number on the back of the switch for future r/r clarification. If someone out there could sweet-talk one of the harness reproducers to sell these connectors we could all benefit but, of course, these people are in business to make money and not necessarily to save any of us any. That's their perrogative and I can't fault them for that, that's standard business. I know for certain that M&H wiring states right on their website that individual connectors are not available, so I didn't even ask. I'm not worried about solving my connector problem and I'll end up with a bullet-proof set-up by using relays on all four blower speed circuits and eliminate the high amperage that the blower speed switch endures even WITH a brand new $350 repro harness. Sometimes repro doesn't mean better, it just means you are duplicating some of the original factory shortcomings.
Thanks again to all,
Louie Hammel

No, that's not the sheet but thank you anyway.
The wire connector housing is the plastic piece that positions the brass female spade connectors in the correct arrangement at the end of all the wires.
Thanks,
Louie Hammel
