Good evening Mr Hagg. Can you please give me the part # for the injector/Jake harness? My truck with Cummins 871, in the last 2 months or so started not working to well. It isn’t working like it should. I have a feeling it’s the harness.
just register your engine ser# on quickserv.com ... its free .. and all the part#'s and drawings are there.

2864399 is for the jake wiring harness. A 871 dont have injector harness.
We only replace the harness when we see oil seeping out side engine. Engine brakes solenoids go bad a good bit. that can be a issue. We also see rocker shafts with a lot of ware and it causes oil pressure to be weak on jakes.. We replace a lot of jake rockers as well...

Update. Passed injector leak down, no oil in the injector harness that i can see. Makes no sense. I start it i have a valve like chatter when its extremely hot 90degs outside and runs decent around 80degs. Sounds really dumb i know. I wish i could get it down to you Mr. Hagg. At this point Im done just gonna drive it. Itll show its issue or Ill buy something more my speed like a n14 or series 60.
