Hi guys,
I've been researching how to do megasquirt wiring on my own, got a free v3 megasquirt but the wiring is a mess. New to the turbo game so had a few questions over all. So currently the megasquirt is wired to the 55 pin connector to the e30 wiring harness. I want to redo the wiring make sure its good and will not be currently doing wasted spark.
I've been reading the megasquirt manual and it says to ground everything to the megasquirt board. So my question was if I run megasquirt to the 55 pin connector would I still need to ground to the megasquirt of the stock grounds will be fine through the wiring harness?
Also looking at the megasquirt theres a smaller board on top is that the wasted spark board? Also does anyone know what the black box is, not sure whats it used for? The wires have been spliced in odd spots so I'm not sure where each goes so if anyone can identify what some of the wiring is for please let me know. Also I've read that sometimes if you wire it a certain way then the coil gets burned out if key is kept in on position.
Thank you ahead of time for your time and knowledge.
