The brake wire is white at pin 31. You should consider using a bypass module (I have used the DB-ALL the last few times on Cobalts). I have hooked it up wire to wire using an Audiovox/Prestige system. The DB-ALL has the brake output that connects to the remote start's brake shutdown. Makes the install a whole lot easier.
