LT1 VATS bypass

Well first off I wasnt sure whether i should have put this ? in here or under the LT1 forum, but anywase I put it in both haha.... My ? deals with the VATS bypass on the LT1 ECU. It turns out when I sent out my compter to be burnt for the specifications of my engine they forgot to burn out the vats so now I'm stuck with a vehicle that will run for only 4 seconds and I was wondering if anyone would know which wires/pinouts on the connectors to the computer are the ones for the vats??? My plan was to locate those wires and splice resisters where neccessary. My other question was I heard of a piece you can purchase that plugs between the ECU connector and the ECU itself that is a VATS bypass module? has anyone else heard of this... I'm going to call summit/jegs and ask about it but I was just wondering if anyone knew of it or used it.

Thanks for the help
