I upgraded my harness to the Super Duty parts, the front side was pretty cooked but the rear was fine. I'm happy to give this to anybody who needs it as I just hate throwing perfectly good stuff away.

Again, I think this is a 1995 to 1997 only part as they changed to single pigtail on the SDs.

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.

Here's the parts list:

https://www.riffraffdiesel.com/under-valve-cover-harness-99-03/

RiffRaff was out of the valve cover gaskets, and I was really hesitant to buy anything except OEM (lots of bad reviews from other knockoff vendors) but I ended up buying Mahle pieces. I see Mahle Behr stuff commonly on the OEM side of heavy truck and the Mahle part number also came up under Victor Reintz. I respect both of those companies products and reputation. I was totally prepared to send them back if they looked questionable in any way, but I think the quality was good and the fit was excellent. I would have spent the money on the OEM pieces if RiffRaff wasn't out of them, but I think these were pretty good and priced really well (set of two was cheaper than each piece :D)
