Hi there merlin and welcome to JA. A celect plus wiring diagram is fairly easy to obtain. You can buy these from cummins or I just found one on EBAY and you can also get one at www.Ebooks.com. Another thing is have you checked your fuses for the ecm they are under a small cap located in the harness between the ecm and cab. There are two fuses and I belive they are 15amp fuses. And also have you checked for any codes
If you need more help just ask
