Re: help with tach install
The easiest way to hook it up is to buy the wiring harness; it plugs right into your control box; there are 3 wires on the other end that connect to the tach; I'm not sure which wires go where, but no doubt someone else here will chime in. If I remember right, that harness is about $30.00 but well worth it. Also, make sure you have your tach at the correct setting; should be 6p. Good luck.
