I want to add a trim gauge, do I need to buy a seperate sending unit or is the trim pre-wired? I bought it on a 2016 Tracker 190 TX and cant really find any info on this.

It should already have a trim sender installed on the engine, but to answer your question the 14 pin harness is wired for a trim gauge,
