How do you replace a ecm module on the 1998 dodge ram diesel 2500?

You can find a ecm at autozone but if not you can find one at the dealer, make sure that you handle this part with care, also make sure the ecm is ready to install, you need this things before installing the ecm latex gloves, you also need to ground your self to prevent any shock with ecm by doing this you need a wire with the one end to the ground of the car and the other end to your self you can buy one at autozone, NEVER TOUCH ECM WITH OUT GLOVES this is a very sensitive and delicate part, unplug the negative cable from battery then unplug all the wires from ECM unscrew the ecm and replace the new one, screw the new ecm plug in all the wires and connect the negative cable that's it your done good luck!!!!
