I'd like to install a tach/mph and possibly fuel gauge on my center console Pathfinder 17t. The motor is a 60 hp Yamaha. How big of job is this and what do I need to know? Thanks for the input.
Picked up a yamaha tach. I have all the wires for the tach, green, yellow and black. I'm left with one orange on the factory yamaha ignition harness. The tach also has a blue and black wire to light up the tach. My question is, can I install a separate switch to operate the light on the tach or does it need to come off the ignition wiring harness? Also what is the best way to cut he hole? I could not find a 3 and 3/8" hole saw, I purchased a 3 and 1/8" hole saw and plan on gently making the hole bigger. Thanks BrettYou'll need to know how to cut a hole in your console
big enough to fit the gauge, without cutting anything else.
And if you have a yamaha wiring harness,
how to find the correct color wires to connect to.
Fairly simple project. Get the gauge designed for your motor.
Follow the instructions packed with the gauge.
