Yes. It was Stephan's (the Mitsu-Tech mod). It used to be on Alex' car (I believe), then Stephan had it (because he bought the car), sold it to the guy in Tampa (who's name escapes me at the moment). I bought it from him. He never installed it because he didn't have injectors yet. The car he was going to put it on was sold to Todd.

Todd can tell you that the harness for the 1g MAS was never hacked into.
Also, the plug was purchased from ebay (by the guy I bought the MAS from), and the plug had not been soldered to a 1g MAS plug (MAS side).

So, I'm 99.9% confident it was never installed after being purchased from Stephan and therefore 99.9% confident it was in perfect working order (unless Stephan sold a bad 2g MAS to this guy, which is unlikely).

EDIT: It just dawned on me that if you wired it improperly you may have damaged the ECU or MAS. I recall that the first time I tried to create a 2g MAS-1g Car plug-and-play setup I apparently had two or three of the connections making contact with each other. When I installed the setup and started the car it died immediately. I removed the setup and installed the 1g MAS and drove off - 1/10 mile out of my complex the car lost two cylinders. I had to replace the ECU.
