I just put SVT seats in my 01 zx3 so I'll be working on the re-wiring project as well. I'll let you know what i find and hopefully it will be helpfull. The only ones I really care about are the air bag ones, thankfully the mating connector should be coded yellow. As for the seatbelt, i'm not sure if it will still go off being disconnected.
