oinojo Posted November 9, 2005 Share Posted November 9, 2005 i received my megasquirt V2.2 but was sent with a complete wiring harness for V3.0. It also came with the V3.0 external wiring diagram. Should i follow that same wiring diagram or follow the old 2.2 diagram? I have an l28et with an 82' Dizzy... also do i need to add any resistors to my dizzy connections? Ive seen a couple diagrams with a 1k resistor. this is how my dizzy is connected. black = ground white = to MS pin 24 green = not connected red = connected to ms 12v wire Quote Link to comment Share on other sites More sharing options...

Metro Posted November 9, 2005 Share Posted November 9, 2005 The wiring for a V3 and a V2 is identical for the basics. The v3 differs by adding a few additional in/out wires for the new things that are built in. Like for the VR sensor and coil driver. If you're confused, go over to http://www.megasquirt.info and look at the difference. I would imagine that resistor is there for a good reason, to lower the voltage, so follow the diagram.

mobythevan Posted November 9, 2005 Share Posted November 9, 2005 also do i need to add any resistors to my dizzy connections? Yes, add the resistor like the schematic shows for the TACH input wire. Quote Link to comment Share on other sites More sharing options...
