Welcome to the forum.....they are very secretive/inventive when it comes to that port... :-D ....have a real good look around........under the harness near the engine front, under the ecu if mounted on the engine/riser, sometimes taped/tie wrapped to the harness wiring. If it has never been used it will be hidden.......good luck with your search, maybe someone with the same package knows exactly where it is located.

I have a 2001 396 with 8.1 Crusaders. The surveyor found but 6 months later I can't find it because i was going to buy the diagnostic instrument and the seller wanted a picture of it. Ill look again after reading the post above.
