Hello, my 01 Ram 1500 4x4 5speed has a very rotten Single cab. I have bought a 99 Ram 1500 4x4 Auto and got the cab ready to take off the frame. I’m wondering if the 99 cab interior harness will wire up to my 01 without any changes ? As for the auto to 5 speed I’ll do the pedal/clutch master and cut shifter hole. Just wondering if anyone knows of other issues I may run into? Thanks in advance for any replies
