Turn signals not working, blowing fuse
Not much to add/
Then that's where it makes the most sense to concentrate next.
Since nothing looked obvious you could take your meter to the wire terminal and confirm the short is in that cable.*
You can also check the wire terminal returning from the reverse switch. The switch should be isolated from ground. But that wire eventually goes to the reverse lights themselves. If the bulbs are good, they are in contact with ground. In other words the ohmmeter isn't going to give you a clear answer on the wire going to the bulbs.
The circuit diagram in the FSM is correct as far as we can tell.
If you find something that differs, then note it.
Everyone makes mistakes. The mistake we found was in the fuse listing, and the wiring diagram confirmed that including the brake lights on a key switched fuse was wrong.
Now think about that reverse light switch. Is this an automatic? If so, what else is on that switch?
and no I'm not saying its inside the switch. I'm just saying to think about the possibilities based on what the switch does.
* You can also remove the individual terminals from that bulkhead connector.
remove the foam seal.
Then squeeze the barb and when its clear it will slide out pretty easily.
If the foam seal is deteriorated like in this photo, DMT has new ones.

Seems like you did that.
IF the problem was solved by disconnecting the connector on the engine side of the firewall;

Including or not including the circuits on the bulkhead connector?
