GOTHALOSISM Posted February 15, 2009 Share Posted February 15, 2009 I was looking at the wiring harness to see how the injectors wire in to it and the harness only has 2 wires. One for inj 1-3 and 4-6. So how do I wire in the injector wiring to the new MS harness? by the way its ms 1 with teh 3.57 board with spark control on a 83l28et for my 76 swap. Thanks in advance Quote Link to comment Share on other sites More sharing options...
S130Z Posted February 15, 2009 Share Posted February 15, 2009 Subscribed. As I too would like to know a bit more about that. MegaSquirt soon to come! Quote Link to comment Share on other sites More sharing options...
AK-Z Posted February 15, 2009 Share Posted February 15, 2009 IIRC, it was just batch firing. depending on the board MS you have, there are 2 injector drivers. You wire 1-3 on one and 4-6 on the other, by default they all fire at the same time IIRC. Its been a couple years since I researched MSnS, so might want to double check first before taking my word for it. Quote Link to comment Share on other sites More sharing options...

It doesn't run yet, but I am fairly certain that is correct. Quote Link to comment Share on other sites More sharing options...
S130Z Posted February 15, 2009 Share Posted February 15, 2009 So your saying that you splice 1-3 injectors together and run it to the one wire? That is what I figured when I was doing my research. And then the grounds go where? Quote Link to comment Share on other sites More sharing options...
Noddle Posted February 15, 2009 Share Posted February 15, 2009 So your saying that you splice 1-3 injectors together and run it to the one wire? That is what I figured when I was doing my research. And then the grounds go where? With my MSII, the injector have power from the battery (via relay / fuse), and the ground wire goes back to MS, MS grounds them out to fire them. There are some nice diagrams out there on how it's wired up, Nigel Quote Link to comment Share on other sites More sharing options...
S130Z Posted February 15, 2009 Share Posted February 15, 2009 I'm sure most of my questions will get answered once I get the MSII and read the manual. Gothalosism, Did you not get wiring diagrams with your MegaSquirt? Quote Link to comment Share on other sites More sharing options...
GOTHALOSISM Posted February 15, 2009 Author Share Posted February 15, 2009 I got the genaric one but it did not mention state on whether 3 injectors wire into one wire. Quote Link to comment Share on other sites More sharing options...

Matt Cramer Posted February 16, 2009 Share Posted February 16, 2009 After connecting the injectors to 12 volt power, on the negative side you'd wire half of them to the INJ1 wire and the other half to the INJ2 wire. Some people put the odd numbered injectors on bank 1 and evens on bank 2, others pair them 1-2-3 / 4-5-6, but I'm not sure there's a real difference either way.

mobythevan Posted February 16, 2009 Share Posted February 16, 2009 There is a diagram in the installation sticky from Tony D that shows how to wire the injectors to megasquirt. Quote Link to comment Share on other sites More sharing options...
