Smartcraft harness

[catch 1]

I have a 2002 Mercury 225efi. I just bought a Smartcraft Tach and speedometer with wiring harness for each. I have a wiring harness that was wound up in the motor cowling part #84-859244 A 1. What harness do I need to connect it to the tach/speedometer?

859244 is the harness for connecting boat side accessories (oil tank, fuel tank, paddle wheel etc.) to the smartcraft system. The plug to put a harness from the motor to the dash is a different plug on the engine (a 10 pin). You would need a 10 pin data harness with a term resistor at one end, a junction box, and a term resistor to put at the end of the junction box after the drops to your gauges.
