This seems to be a proprietary connector, so I’m not sure if there’s an ISO standard designation (like DE9 or RS232). Mouser has these listed as SICMA Sealed Full Interconnect.

Here’s a datasheet. Good luck!

Best guess: 24 pin ECU ECM

Too kind, thank you. I have thought about getting a flea market booth to sell some of my work (and some of my weird junk hoard).

Thanks so much.

Many thanks.

That’s a compliment fs. Thank you.

Visitor Q.

I first saw it years ago at a goth movie night, and I’ve never witnessed a more uncomfortable audience reaction. Would still recommend.

Why’d ye’ spill yer’ beans?
