I can't get my CHRT5 to work. I connected the 2 yellow ignition wires, and the green/red to purple for the MUX. Apparently this is all I need to do. Others on a Ram forum did this and got it to work. I'm thinking it might have to do with the programming with the module. The guy I bought it off of updated it for me, and turned on the 3x lock function. When I hold down the button and plug the data cable, I leave it on the blue light. I then plug everything in. Turn the key to on, and the blue light turns off. Then my dash lights flicker, and I get a check gauges light. Please help.
