Hello Cummins Fam.

I’m new to this forum and to the Cummins fam.

I took my truck to the dealer a few days ago due to a check engine light service electronic throttle control to be exact.

Today I got my truck back and the dealer is talking about replacing the harness and computer which is about $8000.00 plus they want to replace the harness first and take it from there.

If that doesn’t work the computer which feels like a guessing diagnostic.

I can’t afford to pay that much so I’m taking the challenge to check the harness myself and yes I’m mechanical incline.

I need help finding the wiring Schematics for this truck please.

2017 RAM 3500 4x4 Laramie so I can check which cable or cables are damage.

I used my scanner today and I can see the second throttle control keeps cutting off and when that happens I loose pedal respond.

Any help is very appreciated it thank you in advance.
