    I have a 2000 T800 with a ddec4 engine. It does not have a Jake brake and I'm wanting to add jakes. Can it be done easily? Is the truck wired for it? Thanks in advance

    Nice part about KW instrument panel harness is wiring will be there. Have to add switches for off/on and stage switch. Not sure, but don't think your injector wiring harness will have wiring for Jake's. I have only added Jake's to cats or Cummins, so Detroit person have to chime in.

    Injector harness does not normally have jake wires if the engine did not have jakes but I have seen one that did.
