You’ve got to splice the newer style pigtails into your harness. There’s a good diagram for the wiring, it’s not hard, just a little time consuming as there is some shielding tape on the injector wires you have to reuse, and you’ll want to cut, solder and marine heat shrink all of it so you never have to touch it again.
Don’t cheap out on the parts: there’s some pretty crummy junk out there with aluminum contacts and poor fitment.
I’ll send you the list of what I bought, most from Riffraff Diesel. As you can see in the pics below: one side of mine was toasted at the glow plug and starting to effect one injector so I did both sides. The newer style is way heavier and better, especially the glow plug connections on the ends which is a common failure point.
