dexter72 Posted January 13, 2008 Share Posted January 13, 2008 Mobys writeup is correct for ms1 with hei module. If you have the wiring diagram that came with your m.s unit, use that diagram and make your own relay setup. Cygnus has pics of his relay setup on here. I think the post is Wiring up megasquirt. Hope that helps. Quote Link to comment Share on other sites More sharing options...
driftz240 Posted January 13, 2008 Author Share Posted January 13, 2008 mine came with a v3 main board diagram. im just confused by that box, and cant figure out how ms can get the info from the dizzy to make the coil fire. do i need a relay box? my buddy did his without one.

dexter72 Posted January 14, 2008 Share Posted January 14, 2008 If you bought the wiring harness with your megasquirt the wires are labeled, use the exact same wires the diagram shows like you have a relay box in the car. If that makes sense. Run the ignition wire and Fidle wire like the diagram shows for 2.2 board. Check out msefi.com for wiring up a 2.2 board. I have ms2 with a v3.0. Are you using one hei module or two?. Quote Link to comment Share on other sites More sharing options...
