So where do I hook the 2nd ignition wire from the car to the above wires, Thanks.

No, u don't have to, except #10 which is needed for the bypass module.

It is a bypass module manufactured by Idatalink........ ads-tbsl-gm is bypassing vats only thru data wire at the odb2 diagnostics plug under the dash. If you consider to do the doorlocks, then u should consider ads-tbsl-gm1 which will do vats, doorlocks, arm and disarm thru data wire.

It's an immobilizer bypass...it simplifies installation on several GM cars by connecting to one wire at the diagnostic connector and sending data signals.
