    Ok we are taking out the 600 cummins and putting in a C15 cat. What I'm trying to find out is do I need to do any rewiring? The motor I got has the complete wiring harness on it with all the end out of a 2003 Pete 379 and my truck in a 1999 Pete 379. According to my local peterbilt all I need to do is install my new motor and plug into the firewall and will be good to go but I wanted to hear what others have to say before I mess something up

    Thanks for any input.

    I'm not positive, but I think you need to replace tps switch and harness to match. Hopefully somebody else will chime in to confirm

    look at JYs. they sell wiring. You need engine interface wiring for your new engine. If it can tbe foiund - the only way is to purchase new connectors, termilasm wires and assemly wiring harness

    Just did a similar swap in a 97 Pete last year....W900 is right new Tps.... ..as far as the harness goes I would reccomend getting ahold of Ed Mawk at Mawk Industries....some of the pins from the firewall connections could be in different places...not 100% positive...but I'm sure Ed Mawk could supply you with a schematic if needed....he built my harness and it plugged rite in with no issues....If it ain't a Cat its a Dog....hope this helps some...

    Not sure yet I may try parts it out unless i get a good offer. It has a turbo that is 6 months old, air compressor that is 5 months old, 1 new metering actuator and 1 new timing actuator ( each over 700 new) newer water pump, 2 new injectors.

    Serial # is 14000972 it is not motor that came in the truck it was a takeout that was rebuilt and installed in this truck

    The whole motor was rebuilt 1 year ago so all the pistons and sleeves should be good we just spun #4 rod bearing and the crank is shot. As you can tell it has been a very expensive motor for me the last year and I just like my cats alot better.

    If you are interested in it PM me a offer.
