Does anyone have a '04 service manual on CD where they can send me the pictures of the ECM plugs/pins? I have the new Cummins ECM but don't have to service manual to the truck and I need to know what does what. I'm trying to install a BD towloc but the instructions they sent me were for a '03 and earlier. I'm left out to hang over the weekend but this guy NEEDS his truck by Sunday night. PLEASE HELP if you can!!!!:{
