bypassing interlock system
UPDATE. Just dragged home a '74 Duster which I started to junk out. I cannot power it up, but tried to trace some of it for you I believe you need to jumper (EDIT) The yellow with the yellow/ stripe the yellow goes down to the start relay, and those two are connected to the contacts in the interlock relay
