Hi and welcome to the forum

#7 COP (Coil On Plug) is the second from the back on the driver's side. It's also probably the hardest coil to replace on your engine
For some tips take a look at https://www.ford-trucks.com/forums/s...d.php?t=104027
Let us know how you make out with it.

Welcome to the forum mstanton

The 7 in P0357 means #7 coil.
I haven't seen them listed by letters but G would be the 7th letter so that would make sense.

P035x DTCs are often caused by the coil connector or harness as well as the COP itself.
