    Default Cummins swap question.

    I dont know if this is the right place to post this on here. But I have an 07 5.9 Common Rail I want to put in my 03 1500 Z71. I know crazy right and why do it? Its a project and i want to see if i can do it. I think it would be awesome for somebody to roll up beside me and have to take a double take when they hear that Cummins in a 1500 chevy lol. I was gonna ask if anybody knows where to get a wiring harness for this conversion or knows somebody that makes a wiring harness for it. Sorry if this is not the right place to post this. I saw the gasser forum had an option for conversions but figured some of you cummins mad scientists on here may know where I may find a harness

    I would assume you would need all the ecm wiring and trans wiring if keeping an auto and nothing doing a manual valve body.

    Its everything for an 06 07 cummins harness. It shows all you could want for wiring where splices are and what they are and all the different pin connectors its a very useful website. I used this on my auto to nv5600 swap helped out more then you ever would know.

    Do you want to keep factory gauges, AC, and everything else working? Do you have heated seats and all that stuff?
