You really need to check out all the wiring at those connectors. I see some cracked insulation, exposed wire ends and questionable terminals.
BTW, go on over to welcome wagon and introduce yourself.
You said they have been working on the wiring for the past two weeks which doesn't mean anything. How many man hours have they actually worked on it? Are they providing you weekly time sheets showing what was done?
Welcome to the site from Michigan! Is that Tim's collection or yours?
I believe Tim retired. He should take over Stellantis if that idiot Tevarus would get out of the way.
If you have not done any engine internal mechanical work there is no need to do any kind of break in. Just drive it like you normally would and check for any leaks.
