This would be easy if I was at the boat, but it's 2 hours away and I'm prepping to install brand new transom assemblies this weekend. The transom assemblies that came off had both the digital trim sender, and also two analog wires that I think are for the analog trim gauge (which I don't have). Is that correct? The new transom only has the 3 wire digital sender, that is why I want to make sure I don't need anything else.

Do the trim pumps get their limit switch from the engine harness like I suspect?

The smart craft vessel view shows the trim position on the boat so that is all good.
