My ALDL OBD2 plug needs to be replaced. I checked online and found some that were pinned wrong for LS engines. Does anyone have supplier information for one for a 05 cobalt SS LSJ.?

Mouser. Cheap. You’ll need new GT150 pins and the proper crimp tool if you need to replace the pins as well.

The car side is female (holes). The device side is male and has exposed pins.

You could get something like this and cut off the mounted female connector and toss the rest.

It worked! This thing would work on ANY CAR, because it has wires for all 16 pins! My tach, which drives off of the diagnostic connector, using a Dakota Digital tach adapter, now works again!
