what do i plug my boat wiring harness into

[Js30810]

i have a 94 tracker and a 76 evinrude. is there any way to hook up the harness that should go to the motor (for all the gauges). i guess the fuel gauge is all that will work. is there any way to hook up the tach?

not quite following you.The harness from the engine ,has wires for tach,its grey,brown would be heat horn,.Your fuel sender has nothing to do with the ENG harness.It gets power from the keyswitch accy.and the sending unit has a reostat that controls the current ,that tells you info.
