Are you looking for a new one, or you can't find it on the engine?

On the engine, it's on the starboard side. Look for a light blue wire...

Yes on the engine
Is it near the front or rear on the starboard side
Is it possible I need to remove the back seat to uncover the front of the engine to get to it
I have a 2012 Tahoe

I know I'm good, but I don't have the layout of every boat ever made memorized, and as I live in Australia, that's pretty much meaningless.

So I went to the Tahoe boats website... Does it look like this?

Directly above the starter motor. (sorry, took me a while to find it, it's been a while since I worked on these engines.)
