This is extremely good...

Would it be "wrong" to pour some of that knowledge in here?

Hi, looking good!
Could you give us some more details on your transfer switch? Some pictures, a schematic maybe?

Hey, just to add all the info possible in here.
Did you remember to take note or a picture of the part number of the connector you received?

I might have found a solution.
The HS1 series from Heschen appears to support interlocking.
Then it's just matter of finding your preferred combination.
