CharlieK Posted February 16, 2020 Share Posted February 16, 2020 Anyone have a wiring diagram for the 2000 E7 Etech Unit pumps? Number 3 is having a problem, and It's spending a lot of time with a miss. Had the same problem a few years back, swapped out the unit pump and it didn't fix it. Brought it in, and they ran a new wire which fixed it. Said I should probably get a new wiring harness. I'm hoping with a wiring diagram, i can find and string a new wire for #3... before the weekend is over!

Ezrider Posted February 23, 2020 Share Posted February 23, 2020 i replaced the harness on my 2000 there was quite a few places the injector portion of the harness was chaffed cracked ect. i don't have a diagram handy to help you out but. once you get it fixed for now i would consider planning to replace the harness in the near future. i used to have all kinds of phantom codes that would come and go on my truck new harness solved all of that was a worthwhile repair imo.
