    I need to add a tach on my new motor to see where its at and was wondering how difficult this is or should I just pay the dealer? Motor is a 2009 Mercury four stroke 90 hp on a 2008 Crestliner CXJ 1870. I figure its just a matter of mounting the tach on my console and then running the wiring to the motor in the wire loom on the boat but where do you hook it up on the motor? I don't want to cut or modify any wiring if I dont have to. Chris
