Replacement CAS wire terminals
 

After searching on "CAS connector" "CAS plug" and other variants, I'm coming up blank on where I can source replacement connector terminals for the 4-pin CAS plug on a '90-'93 NA.

I'm redoing my engine harness wiring as part of my swap to an AEM EMS and discovered a hack job wiring splice job from a former owner just aft of the CAS connector plug that I'd very much like to fix cleanly. By cleanly, I'd prefer to simply replace the terminals and wires all the way back to the ECU connector than simply re-splice new wiring to an old brittle wire stub on old questionnable terminals.

Anyone have part number info on these connector terminals and where I might source? Digikey? Mouser? Ballenger MS?
