1970 181 to a 1978 181 different engine harness?

Thank you for the info, I have been searching the web for manuals and the one I can find won’t download, I have tried for 2days now

Ebay seems to be the only place for oem manuals these days. I would guess you're looking for #2 and #3 for both packages

Found out the gimble bearing was bad so replacing that, would it be better to have everything mounted to the boat before I do that? Or can I do it without the motor being connected to the gimble housing?

Install doesn't really matter, although as others have said you'll need the engine in there to align it. However, to remove the old one, especially if it's rusted in place, it's much easier with the engine out of the boat. You can just use your alignment tool and a BFH to knock it out from the inside.

You probably know this distinction already but just in case...make sure as to whether you are talking about your "gimbal bearing" as opposed to your "gimbal ring"...two different animals, just a heads up as others have confused the distinction in past posts and concerns.

Oof

You can't disregard the aluminum casting that houses the bearing. If the bearing is that much corroded in place I'd be concerned of the integrity of the gimbal housing itself

Visual inspection of the gimbal housing/bearing ought to be enough to determine worthiness of repair. I've never been unable to remove/install a gimbal bearing in a suitably sound housing beyond the use of a slide hammer and correct installation tools

Your description especially based on no coupler/engIne presence using an alignment bar (not its intended use btw) to aid in gimbal bearing removal piques doubt

It's literally a one minute job knocking it from the inside. You aren't touching anything but the old bearing. The alignment tool is a giant piece of steel, you won't hurt it. But feel free to use something else. Curious as to what exactly you're worried about?
