Stop in for a cup of coffee

Agree looks like the bracket I just took off. No way wires were running through it. Just looking at the one I posted earlier you can tell its right. Only three wires on that side to run through hence three wire bracket. Probably use a little wire spacer to make it look clean.
Maybe they made a running change or change before actual production.
The bracket you took off and shown in the photo might be for another 383 application
