Wow! pretty busy under there with all the emissions. This topic comes up often, and I'm guessing you do not have to pass air care? You can disconnect and plug, but it might affect the running of the engine since you have electronics. That being said,these older trucks are more forgiving when omitting the pollution components, so the only thing you may notice is more smell from the tailpipe.
