There several version the Delta two poles seat switches and I have seen diagrams indicating shorting strips. Well I finally ran into one using the Delta 96549-OL housing that was shorted even when fully plugged in. Here is what the shorting strip looked like that was used on the Delta 6444-83 switch. I simply removed it by removing the Delphi 12066214 terminals first. It wasn't necessary to replace the $45 wiring harness but I would have liked to replaced the connector housing to maintain the shorting function.
