I don't know how he did it. All I know his is a '98 GS and he has installed a ZEX kit on it and it definetely works. The only problem I believe he ran into was the volatge from the TPS not being strong enough to activate the system, so he hardwired it to a toggle switch.
Here's a pick of how HIS Eclipse looks now with the STAR Stage 2 and ZEX control module (bottom right) still hooked up and good to go. I know shit about Nitrous so don't ask me how he got it to work.....
