    Almost there but I need help from you guys
    It’s a 3406 with a 40 pin ecm (not j1939) compatible
    Everything is working on the truck, the only thing that we can’t figure out to work is the odometer and the trip miles hours of the engines are there everything is there working perfect.
    I was told that I need to set some parameters off from the CECU vía ESA FROM PACCAR IF IM NOT WRONG
    Such as
    Vehicle Software Parameters
    For proper functionality, please set the vehicle parameters as follows using ESA:
    Make sure to set engine make to the proper engine (for DDEC use CAT)
    Outside Air Temperature (OAT) is set to: SENSOR
    RPM sweet spot set to: OFF
    Water-in-Fuel sensor set to: OFF
    Brake lamps on with retarder set to: OFF
    DPF functionality set to: OFF
    DEF gauge is set to: OFF
    Clutch switch set to: OFF
    Engine shutdown protection timer set to: OFF Downhill speed limiter telltale set to: OFF
    Engine de-rate and shutdown warnings set to: OFF Green House Gas (GHG) set to: OFF
    PTO total fuel used diagnostic set to: OFF

    Any info will help thanks in advance guys

    I dont belive the cecu has provisions for hardwired tach/ speedo/ hours. Needs to be a multiplexed system.
    Kustom truck harness gets around this by adding an ecu to their harness that converts all the anolog signals to a multiplexed signal the cecu can read. 70 pins are alot easier to make work as they are datalink ready
     
    SAR, 062 and Oxbow Thank this.

    I emailed mawk ind about a harness to put a 1lw in a 07 379,and he said I would need a "box" to make it work. I asked what the box was but never got a response. I'm guessing the "box" is the ecu your talking about?
     
    WyoVac Thanks this.
