Does ignition control module color matter

Your truck has DIS (not EDIS), some versions of DIS used a cam position sensor for SEFI fuel injection (yours doesn't), I'm not sure if the modules are the same or plug compatible. You would have to pull the part number off and go to a good parts website to decode like Rockauto, etc.
