You just need to remove the wires from the ecm connectors for those applications that you are not using, they do not have to be hooked up to anythingafter Rockrcrawl modifies the PROM.

well the nitty gritty is about to start. on the C203 harness I have (87 4cyl plug from my parts car) is missing the "J" and "K" wires for the injectors. do I have to use wires here for my new 4.9 harness?
