    2007 Crown Vic PCM Bench Harness Schematic Needed

    Hi,

    I just purchased HPtuners and I'm new to this forum. I have been searching without any firm guidance on wiring a bench harness for a Ford 2007 Crown Vic 4.6L 2V. I am building a 1964 F100 and I bought a 2007 police interceptor donor.
    I have the wiring diagrams manual for this vehicle but I need help with how to wire a bench harness for doing HPtuner scanning and flashing to the PCM. Can anyone please help me by sharing wiring diagrams to make a bench harness and any specific things I need to be aware of.

    Than you in advance for your help!

    Did anyone managed to get this working?
    I am trying to do my own bench harness for crown victoria 2006 4.6L 2V

    *I get ID and DTC with my launch X-431 diag tool
    *I can read ECU map with my kess3 tuning tool
    *I can ID My LS1 ECM so my MPVI2 should be ok.

    but when i try to ID Ford ecu i get "Detect protocol failed"

    I checked Wiring in Autodata and on
    https://performanceparts.ford.com/do...-463V_54SC.pdf
    Page 15

    Ground on pin 10, 47, 48, 49, 50
    KAPWR pin 45
    Switched power pin 35, 36
    Can High Pin 11 (OBD pin 06)
    Can lo Pin 23 (OBD pin 14)
    FEPS Pin 44 (OBD pin 13)

    I had to put 120ohm resistor between Can hi - Can lo to get communication to work with launch and kess3. butt still no results with HPtuners.
