Tach Wires

I have a 703-4820-17-10 control box,I just bought a Tach pn#6Y5-8350T-82.My ? is do the wires that are on the control box (not 10 pin connector the other batch) go to the tach, if so what are the part# for the harness for the trim, RPM and oil level, ect...........If some could e-mail a wiring diagram to would be great..............

Thanks

You will need 6Y5-83553-N0-00 gauge power harness to connect gauge to 703. If your motor is 1994-2004 you will need 68F-82553-70-00 Trim/Oil harness(connects engine to tach). If your motor is 2005 or newer you will need 6Y5-83653-10-00 Trim/Oil harness.

Thanks for the info......... the motor is new.. so the 6Y5-83653-10-00 is the Trim/Oil harness, is it the RPM harness also? and from what gather i need the 6Y5-83553-N0-00 gauge power harness also? to sum it up i need both harnesses? Last ? is some way to get a wire diagram for the motor/control box...............

Thanks for your help
