My MAP sensor connector is broken, and needs to be replaced but didn't know where to look. I don’t suppose anyone has a bill of materials for the engine harness with connector part numbers? I could build my own harness with better quality.
[Edited MAP, not MAF]
Alternative would be to buy the replacement in “pigtail” form - a genuine AC Delco or GM connector w/ short lengths of required wires already connected. Cut old connector off and splice new wires to harness. Shoebox has the part #’s (scroll down toward bottom of list on right side of page):

Surprised the quality of the OEM part is in question. In 20+ years this is probably the first time I seen someone post an issue with it.
I haven't chance to research where I can get it yet but this is what's up. I'd prefer to keep as much of the vehicle harnessing as possible, by de-pinning and repopulating the conductors into a new connector rather than lap soldering in a pigtail. These connectors shouldn't be single use and should have a method/tool to insert and extract the contacts.
If I had a full set of good/new engine harness connectors for a 94 M6, I'd order the wire and build my own harness to my standards.
Getting closer. There should be a tool kit I can buy that has the proper GM picks for extraction. These, along with the crimp tool for the contacts/terminals, I could repair/ or build a new engine harness.
I'll order it and a GM/Universal tool kit that has multiple picks for terminal extraction and R&R the connector.
Anyone have a recommended electrical connector tool kit for GM harnessing lol? I see for crimping terminals uses weatherpack and metri pack crimpers. I'm still searching. I'd love to have access to the tools the GM techs or outsourced techs had when manufacturing these harnesses.
The connector repair procedures are covered in the factory service manual. Also has details on each connector, not sure if it includes part #.
You could also de-pin the replacement pigtail and use only the connector if you want to avoid splices.
I also misread your original post and was thinking MAF connector. The MAP connector is one that tends to become brittle and fall apart. My 94 was replaced around 2002.

Yes, that's the plan. I ordered the pigtail. Looking for the extraction tool/pick at the moment. Probably going to get a kit that has several and find the one that fits.

I mistyped it at first as MAF, then edited later when I re-read it 😄
I recently R&R'd my intake manifold gaskets and noted my wiring and loom needs to be cleaned up all over the engine bay. Clips that go around loom to anchor harnessing are broken/worn. Loom is brittle comes apart in many areas.
OK.... I was worried old age and failing eyesight made me mistake MAP for MAF.
Time is not kind to plastic. I need to replace the bump stops for my hood. The threads just crumbled and they fell off. Fortunately they seem to be readily available on the web.

I have the regular bump stops down and to the right of my hand, but what about the thing I'm pointing at? I used to have 4 of them, now only one. Yes, aware my light bar is cracked. Did that 10 years ago removing and replacing it without taking the front bumper off first like a dummy (forced it).
Removed and replaced the connector, saving the vehicle harness wiring rather than splicing into it. I used the tool in the pictures that I picked up from O'Reilly's. You can see on the terminals they have two locks on the barrel that the tubular release tool slides over. Make sure you slightly bend the terminal locks back out before inserting them into the new multi-pack or weatherpack type connectors so they lock.
Connector removed and replaced. For the MAP connector, you need the longer extractor onnthe tool because the terminal locks are deep in the connector housing. Terminal release tool. Terminals that were extracted from the pigtail I ordered from Amazon.
