Great to see there is still some interest for the relay! Life got a bit in the way so the progress has been slow, but it is not dead.
I plan to just mold the pcb and wire harness in polyurethane potting, to keep the environments out. Very easy to do.
It wont be so serviceable without creating a mess, but being solid-state it should not need it either.
For connectors we have two choices, either a new sealed type or the original plug. I have bunch of the original connectors brand new now so sourcing is not a problem.
For that matter, if anyone needs new male or female connectors or just new crimps pins, drop me a message.
