    It is a multi part harness, once we figure out which part(s) we can go from there.

    Replaced my engine harness a couple months ago injector/sensor harness was around $500.
    Ambient sensor was buried behind the wiring harness right side of ecm. Had to look behind wires. If original it's bolted to the block.

    The harness isn't cheap. Thinking mine was 750 or so with the part that goes to the batteries that has the fuses for the ecm in it

    But if I get 10 years out of it and my truck becomes more profitable it is a minimal investment.

    Also, get a 2nd ecm for spare. Easy to replace. Expensive to buy on the road.$3,500. Don't forget to have the spare programmed.

    The one on here now is about 3 years old, but I have considered a spare...

    It was replaced before I bought the truck. I believe it was purchased at the Freightliner dealer in Waterloo, IA.
