I have a 2002 F50TLRA 4 stroke engine. I want to install a digital tachometer (has the trim, fuel, oil, etc.). Where can I get a wiring diagram that shows the connections to the remote control and everything. Also, is the tach signal coming from the ECU or do I need to pick it up off of the retifier. I already have the Yamaha tach and the two sets of wires.

The short wiring harnes in gauge kit connects to control box ( or key switch if switch is mounted in dash). The green wire connects to green, yellow to yellow, blue to blue and black to black. The long wire harness connects to engine match the connectors to engine connectors. Set the dip switch's in gauge to 4 stroke eng., 2 wire trim sender and 12 pole alternator.
