Frank C 0 Report post Posted February 12, 2016 I see Mercury has a new auto trim system out that can be added to newer boats with sterndrives and smart craft and DTS. The mercury literature says it can be added easily as it just connects to the engine harness. Has anyone investigated this any further and where would the engine harness be typically? I have a 2014 340 SY. Share this post Link to post Share on other sites
