After 8 years I'm finally trying to get the cruise control to work in my Dakota with the Cummins ISB170. The Cummins has the analog inputs for the cruise functions and can just be turned on with Insite. That part is easy. The Dakota has the cruise switches in the steering wheel and its a 2 wire output with variable resistances for each function of the switches. I'm looking for a control module that will take those variable resistance values and turn them into switched outputs to run the Cummins cruise.
