Hello and welcome to JustAnswer! I'm Nick and I'll be helping you out today. You'll need to either buy a new harness (a glider kit builder might be able to help you out with that) or you'll need to make some major changes to your existing harness. Can you provide the last 6 of the Peterbilt VIN? I'll pull a wiring diagram for the original truck and I'll send you a diagram for the 40 pin ECM. You may also need to change some programming on the Cat ECM and the cab controller if your Peterbilt has an ICU or CECU.
