TRunk light switch
I think functionally the door jamb switch will work. The wire will hang down a little, is all.
On a related topic, for a weird example of a Mopar engineering quirk, look in the trunks of 67-69 Barracuda fastbacks. You will notice that some have a single latch for the fold-down panel, and others have two latches. The center latch catches where the trunk lamp would normally fit, so single latch cars have the lamp location offset to the side (even on cars with no trunk lamp). But there is a completely different piece of sheet metal welded into the body above the trunk opening for the cars with two catches, with the lamp location in the middle (whether it has a lamp installed or not). What's weird is that the one- or two-catch panel isn't a year-related change (either one could be on any year), and it doesn't correspond necessarily to light package or no light package, either. Yet they had to tag that as it went down the line so the right body would get the right panel.
