I got this wiring info for a 2002 Grand Am and as far as I know it's the same as a 2003, which is the same as a 2004, correct me if i'm wrong: (see below dotted line)

Question is about the double iginition wires. Would i simply tap both and tie into the single wire going to alarm brain? would i have to diode isolate both and then tie into the single wire for the alarm....if i helps, i'm not using a starter kill - I don't want to mess with the passlock system.

Notes:
NOTE: This vehicle has the passlock II immobilizer system that, when adding a remote start, must be interfaced with. Use DEI part 555t or 555L. *1 Remove the radio, without unplugging it, to access the ignition harness. *2 Lock requires a negative trigger, and unlock requires a negative trigger through a 1,500 ohm resistor. Must use relays. Must close doors to lock with a single pulse. *3 Requires a high current ground. Use a relay. *4 The lt. GREEN/ black is located in the drivers kick and catches only the drivers door. The lt. blue is located in the harness coming from the drivers running board going under the drivers seat and it catches all other doors. Use both door trigger wires and diode isolate each. On the 2 door the lt.blue is in the passenger kick. *5 The ECM is located under the left side of the dash to the left of the column.
