Built in August 2017 question/s

My Crewmax was built in August of 2017. It seems to have pre and post August 2017 wiring and connectors. I'm chasing a ECU-IG1 7.5A blown fuse issue (7.5A fuse is a pre August 2017 feature as far as I can tell) issue and am getting lost. Is there an easy way to figure out which wiring diagram group I'm supposed to use?
Thanks in advance for tolerating my mud between the ears issue.

Well your fuse boxes are marked with what fuses are where.

you have a box under hood and one under the driver dash, I usually check both places when chasing fuse or electric issues.

Thanks for the link. Turns out that is the one I found before, when hunting for diagrams due to the Christmas tree dash lights and a P0500 code.
The fuse in question is in the box under the drivers dash. My challenge is decifering which wiring diagrams and connectors I should be chasing as my truck was built in the month of pre and post on the diagrams.
