Is it an 05 from a Durango or a Ram. The bus system is different. What year is the motor and trans. If you have an 05 from ECU from a ram you will be good. I think the Durango had MDS. I’m not sure the question on the brake switch. I used from a Ram. Not a used one, it has a one time activation on it. I would talk to Chris at Hotwire for your harness. Tell him what’s going on with it. Have you put a scanner on it to pull the fault codes.
