Default CAS connector or pins

I have had a random issue where my car will cut out and not restart for a few minutes. Then just start working again with no changes made. I never have a laptop hooked up when it happened and it happened on my MS2 and spare MS1 box.

After completing my turbo install I couldn't get it started. It wasn't getting any CAS signal. I thought it was the solder joints from the CAS wire extension when doing the 1.8 swap but it looks like bad/old wires right at the connector on the CAS. If I push on the wires right at the connector it will get the signal and it will start and run.

I can't seem to find a new CAS connector for a 90-97. I would even settle for some new pins so I can rewire it all. Does anyone know where to get either?

I'm an idiot. None of the good threads showed up when I searched on my phone. Found them when searching on the laptop. I figured Google would show the same results but I found different threads with a mobile vs regular search. I am still not clear on the 90-97 CAS connector. The connector spreadsheet shows one for teh 99-00 CAS, but not the earlier one. I read somewhere that the 1.8 coil connectors are the same as the older CAS, but I need to check. I kept the 91 coils so I don't have any to compare to right now.

I got two 1.8 coil pack connectors from Panicmotorsports. It is real nice to have them locally. These only come with 3 of the pins connected, but had some additonal pins so I just removed the plug on the 4th pin and made my own connector to test. I got the car running. Now I am going to gave to find some new pins so I can can pull all new wire from the CAS to the MS since this appears to be a critical input and loosing it means going home on a tow truck!
