The answer is most likely yes to remembering one as I remember way to many posts from here. Although you may remember it, this doesn't mean you will actually be able to find it... Sadly...
I remember reading that the engine harness is a standidyne part and that the replacement harnesses had better wire and connectors. I don't remember where I read it though. Diesel pro may have posted it over at the place.
I did not recall that they mentioned any part number for the Injector Harness.
My understanding was (I could be wrong) that the injector harness is the same one that the PMD hook into (at least one of the plug). If you buy a new Stanadyne PMD, it usually comes with it.
