Re: omc wiring help for gauges

Those same connections are provided in the wire harness if you look for them. Splice into them. OR -- go to Radio Shack and buy individual pins. Solder the tach wires to the pins, cover with heat shrink and plug them in. You can even go so far as to make your own plug using a wooden dowel and Radio Shack pins. Done it many times. Drill matching holes in a piece of dowel the size of the pins. Wire the pins, stick them into the dowel so they protrude out the front. Epoxy the pins in place and plug it it. Or spend about $30 bucks for the harness.
