Well just got my 90HP ELPTO, Brand spanking new 
Got myself a tach from a buddy, it's a teleflex model #57333-001 no instructions. Also picked up a wiring harness for the control box. From the instructions on wiring harness Gray = Alt, Black = Ground, and Purple = 12V. Only problem is the tach has IGN, GRD, and Send. <br /><br />Would I be correct in the following wiring configuration.<br /><br />IGN = Purple = 12V<br />GRD = Ground<br />Send = ALT <br /><br />Tach also has a dial setting of 2P/4C, 3P/6C, 4P/8C, 5P, 6P<br /><br />Does anyone know which setting should be setup for my 2005 90ELPTO w/ 3 clynders?<br /><br />Thanks for your help in advance.<br /><br />Paul
