I've been handed back a bunch of different megasquirt stuff I bought from different people a long time ago.
The summary thread got me some of the way there with this stuff, but I was hoping I might get clarification on some of these bits and how to separate them to move on to someone who may find them useful.

This looks like an MSIII:


I think this is a DIYPNP... board says v.3.0


What are these things and should there be one for each of the ECU's?


Which one would this go with?


All the things together. Any direction is much appreciated!

 

MS3, MS2 generic build, relay board, 2 JimStims.

 

Ah Jim stims gotcha.
Thank you muchly Revenant!
