I don't know the correct term for this red cap that appears to keep the blue seal in place, but one of my adapter harness connectors was missing it. I don't think there is any harm in running it like this but I want a second opinion.

 

those are the pin locks. they keep the pins from coming out. see this thread https://www.miataturbo.net/general-m...-70034/page19/

 

Pin locks? That can't be, it would make too much sense. Thanks.

 

I have reached out to Nigel at Flow Force and he is sending me a replacement adapter harness. I am very pleased with Flow Force and I am always happy to support companies that support the community.
