Was attempting to pull the pins out of the white plastic barrel connector to remove the harness from the mirror and tighten the screw that holds the base to the back, but damaged one of them beyond repair. Roger can't find the pins in PET, so I'm looking to the forum for assistance.

Does anyone have spare pins, or a part number from DigiKey (or similar) that I can order from? It's the female pin on the body side of the connector. I believe I need 6 of them. Any assistance is appreciated.

Edit: oops, what's below is info for the GTS mirror connectors; they're different than what came on your '87.

I believe what you're looking for is 999.652.711.10 (female).

999.652.710.10 is the corresponding male pin.

I think these are standard D-Sub pins.

The best match I could find for the female part at Digi-Key (also making use of the fact that the pin housings are marked "ITT") is ITT Cannon, LLC 030-2488-016 (Digi-Key part number 1003-1936-ND).



The corresponding male part then would be ITT Cannon, LLC 030-2487-016 (Digi-Key part number 1003-1935-ND).




I might have some spares. I'll check and see.

A possible lower-priced alternative by a different manufacturer, but with the same specs, including the 0.76 µm gold contact thickness:

• female: TE Connectivity 166291-1 (Digi-Key part number A104950-ND)
• male: TE Connectivity 166293-1 (Digi-Key part number A104951-ND)

I have 15 of the N0175641 male pins used for one side of the connector of your flag mirror, but I don't have any of the female side, nor can I find the Porsche part number for those, either. It appears to be just part of the wiring harness for the door and isn't further broken down. But now that I've got some of the N0175641 pins in front of me (and I see that they're marked "AMP", so that helps narrow things down a bit), I might be able to find them at Digi-Key and find the corresponding female part.

Here you go. My best guess is that these are TE Connectivity AMP Connectors "Multimate III+ series" contacts. There are a lot of contacts with very similar specs, but subtle differences. You have to look carefully not just at the specs in the tables, but also compare the engineering diagrams.

This is my best effort at getting the closest match.

• Female, 0.76 µm gold plated: TE Connectivity AMP Connectors 66100-9 (Digi-Key part number A16080CT-ND)
• Male, 2.00 µm tin plated (tin plated is what was originally in my car): TE Connectivity AMP Connectors 164161-3 (Digi-Key part number A122976CT-ND) (note: this might be the same as Porsche part N0175641)
• Male, 0.76 µm gold plated (that's what I'd use) TE Connectivity AMP Connectors 66098-9 (Digi-Key part number A1340CT-ND)

Important: The above contacts are the versions for 16 to 18 AWG (equivalent to 1.31 to 0.82 mm²) wires. Based on my measurements of a Porsche N0175641 contact, I believe that's what they're using because there are, as I recall, some cases with the mirrors where two wires need to be crimped into one contact.



It's possible, though, that at least for some of the wires (that are only 0.5 mm²) that the versions for 20 to 24 AWG (equivalent to 0.52 to 0.21 mm²) wires would be better, in which case you'd go with:

• Female, 0.76 µm gold plated: TE Connectivity AMP Connectors 66331-8 (Digi-Key part number A1661CT-ND)
• Male, 1.27 µm tin plated (tin plated is what was originally in my car): TE Connectivity AMP Connectors 1-66332-4 (Digi-Key part number A31996CT-ND)
• Male, 0.76 µm gold plated (that's what I'd use) TE Connectivity AMP Connectors 66332-8 (Digi-Key part number A1648CT-ND)

Also (not important to you, but perhaps of value to future searchers from other automotive communities) I see that two of the old flag mirror connectors (housings for the above contacts) I found in a leftover parts bin have the following VW/Audi part numbers: 171971999C (4 position male housing) and 171971998E (6 position female housing). For some reason, it seems that I didn't save any other mirror connectors from when I did my flag-to-GTS mirror upgrade many years ago.

No P/Ns from me but I'll offer this:

Last summer, I tried to get pins for a P-car wiring issue (996/Boxster) and nothing I could find would work. (I deal with this stuff at work so some insights.) In the end, I got parts harnesses, scavenged pins from those and spliced them in.

With tens of thousands of pins to choose from you might think it'd be in there. Then again, there's no reason to be making pins that were last installed 22 years ago, or longer.

Ed is the best.

Oh yeah... one other thing, in case you're not already using one, you should be using a proper extraction tool.

The TE Connectivity AMP 305183 (Digi-Key part number A1329-ND) is one possibility. See also its instructions. There are some other multipurpose tools that might work, too (e.g., Lisle 56500). I've got at least one of those (or something similar), but I can't find it right now, so I can't recommend a specific one.

And you'll need a decent crimping tool when you're ready to crimp the new contacts.

Got the proper extraction and crimper... for some reason one just did not want to come out! So, instead of having 1 short cable that's over-stressed, I'd rather cut them all to the same length and use new pins.

Ed, tons of good information there! Hard to decipher which pins are appropriate for the barrel connectors, though. It looks like your first two posts are for GTS connectors, or the dual flat MOLEX type connector on the later flag and aero mirrors.

The third post looks somewhat similar to the barrel connector pins. I'll snap a pic for reference if anyone searches this post, and to compare the pics. From memory, that pin you posted looks like a two-piece assembly and more complicated than the pins that came from the barrel connector. We shall see... I'll update this post later.

Ed Scherer

What connectors are you calling "barrel connectors"? I thought your car would have the flat, white, 4 in-line and 6 in-line housings, unless you've upgraded to the round connectors used for the GTS mirror. In either case, you should be covered: posts #2 or #3 provide info for the smaller contacts used in the GTS Aero mirror and the round housings, and post #5 covers the pins used for the 4 or 6 position flat white connectors.

I've examined all of those housings, so I'm pretty sure that the various pins I referenced will work.


Unless there are yet more types of connectors; I hadn't considered that possibility. I thought at least all S4s/GTs would be the same.

Ed Scherer

Hmmm... I just checked and see in this diagram a reference (#18) to a 7-position housing part number 803971980 that looks round. Is that what you have?


Here are some photos from a PP thread. Do these look familiar?

If so, these are almost certainly different contacts. I'd need to get some really good photos and possibly measurements of the contacts.





Also, if those are the right "barrel connectors", it looks like you can get the whole thing (female side 803971979) for about $8, including the housing and pins. It seems to be a common part on many 80s/90s German vehicles.

See a VW option that specifically mentions that it includes the contacts. Male side (803971980) is also available, complete with contacts.

Yep, that's similar to the barrel connector I'm referring to. Here's a picture of the pin. I'll have to take a picture of the connector now just to confirm that's the same. A center pin is not on this connector, even though there is a hole for it. Also, there is only 1, not 3, triangle tabs on the contacting surfaces.

After careful measurement of the crimp wings, it looks like Digi Key connector part number 66399 will work perfectly. Any of the options will work, as they just differ in the thickness and type of plating on the connector.

Got the pins... all looks good! It's a match.

Ed Scherer

Fantastic! Good to see this work out. And good information for future searchers.
