Correct connectors for GM OBD - '94 Corvette LT-1

I have a 16-pin ALDL connector used on a '94 Corvette LT-1 that needs to be wired correctly.

Here's a picture (of one wired correctly, not mine):

What I'm looking for is the part number of those brass connectors inside the plastic housing. NAPA or CarQuest or similar would be fine. I'd ask there, but they never seem to know little stuff like this.


And just for fun, here's the wiring schematic from chevythunder.com:

GM Dealers have a parts book that lists fittings connectors etc. You may have to buy 100 or so but they are avaiable. you will have more luck with an established dealer where the guys also speak books not only computer. Also might try Terminal Supply in Troy Michigan

Pigtails

Hey Man, Check out the pigtails $15.00 for obd 1 or 2. You have to have the correct crimping tool and a pin insertion/removal tool to make you're own. Nolan

Here's the page at EFI Connection. I have the correct crimping tool and the pin insertion/removal tool is just a small, flat blade.

http://www.eficonnection.com/eficonn...spx?ItemId=361

And the connectors are offered in two wire gauge sizes, 18-20ga and 20-22ga, I need the former, P/N 100-00138


Now that I have the "correct" name for these things< i can check at the dealer/NAPA and see what is available locally, or order from EFI Connection.

Thanks!

A search of the TS website catalog turned up empty, but thanks for the link.

And I never thought about this: the wrecking yards are full of pigtails.

Yep, My current project harness got real mangled, burnt and cut. Some of the repair pigtails are relatively cheap, some are real expensive. I did a little junkyard hunting, but found no LT1 equipped cars locally. On a couple of the missing plugs I plan to just butt splice the wires together to save the bucks. I don't plan on taking it apart after I put it together. olnolan

No parts store localy has these connectors. I wound up at the Chevy dealership where my cousin works at the parts counter.

They were not listed in his computers, but it seems that every dealership has some small parts trays of Delphi connectors that are not for sale to the general public. I found the connectors there, but I had to look through 20 trays and many of the connectors looked similar.

So, if you have a connector as an example, you should be able to find anything if they'll give you access to the Delphi parts trays.

And again, there's always the junkyard full of "pigtails", but I hate doing that.
