I bought a 2000 Peterbilt 379 with a 6nz in it. When I bought it the cruise wasn’t wired up. I found the harness which is in the picture. But 2 wires are cut. One wire is numbered EE27. I don’t know what the other is. Anybody familiar with this wiring. I’d like to get my cruise working. As you can see six wires come out of the harness four go to a plug and two are cut.
