Have been dealing with a cluster-f of wiring for my Megasquirt install. Seems the previous owner repinned the trailing coils at some point. They had unplugged them because they could never get it to work, but found out between the guides that somehow two of the wires in the plug under the hood were swapped and why I was having so much difficulty getting it to work.

What I am looking for is a clear picture of the coil side of the4 wire, 2x2 plug, specifically the orientation of the red and white wires to confirm that I have it in the stock position again.

 

Not sure exactly which one ya need, but here is the 4 pin I think you're referring to:

 

That is it, thank you much Θ7

Seems it was correct, then I must have swapped the A and B spark wires on the megasquirt, this will be the 5th time I have looked at them, unless the guides are out of date

 

You probably know this already, but 87's could have had low impendence injectors and a resistor pack.. .. . .If the previous owner could never get it to work, checking the ohms of all 4 injectors is worth doing for the sake of it just so you know what you are dealing with. . ..You could be doing everything right and previous history is getting in the way.
