04 Ram 5.7 into a 71 E-body. I have the engine and a stripped wire harness and computer. My questions are, [1] what other parts do I need to complete the drive by wire set up ? [2] What would I expect to pay for those parts ? [3] Where would be a good place to find these parts ? [4] Is there a better setup that I can use insted of the DBW that don't cost an arm and a leg ? If so, do I need to get a new computer.
