About 15 years ago I did some work on my 87 Dakota. I built a 3.9 4bbl. with electronic ignition. I would think a 440 with electronic ignition would be wired in the same way. I remember the instructions from mopar said to connect to the dark blue wire in the main harness. You should be able to find a copy of the instructions on the net somewhere. Most everything else should pretty much plug in
