I just cut the wires off at the connector no reason to let em stick out or anything but I'm not going to sit there for no reason and pop all that s*** out when all I gotta do is snip a bunch and be done with it.
look up the wiring diagrams for PCMs as far back as 96 all the way to 2003 all the platforms and you will find there are three variations of power and ground feeds to the PCM when you take a multimeter and check the pins of these terminals you will find that multiple pins are connected to each other ground pin xxx is also connected to ground pin xyy. ..switched power pins are also connected to other switched our pins same with the hot feeds
