I hooked it up to the ground wire on this injector
(last on the left)
Onto this ground wire from that injector
And when I start it up that injector misses completely..
This whole MPGuino is starting to piss me off a bit.. I've spent hours on the case for it and it looks terrible and I can't even figure out how to wire it up right.
But hey, at least it powers on right.
Thanks for the help so far btw. I appreciate it.
