LS Wire Harness Connectors

[67see10]

Is there a list of part numbers for the connectors on a ls harness? I have more than a few broken connectors on a harness that I need to replace.

[Gregski]

for the two or three that were wonkey on mine I just went to the local PnP and snipped them off of the harness, I made sure not to jack up a good one so I found some that were already torn apart, I figured better to replace OEM connectors with OEM rather than aftermarket junk, but simply Google it we find EFI:

efi connection is great for replacement connectors. You can get empty bodies and pins as well as pigtailed connectors if you don't have the right crimp tools.

Mouser Electronics is the place but you will need to know the Delphi part numbers.

An Alldata subscription for your donor vehicle will give those part numbers. At least it worked on my 2010. There's numbers listed for each connector and terminal.

No charge.

Here is a link to the Delphi parts catalog. It doesn't show specific applications, but it does give part numbers.

Agreed. This has most any Delphi part number needed for an LS swap.

Edit: Jinx! Willie found another catalog scan at about the same time.
