It's not a diesel, but I asked this over in the Pontiac Forums and haven't got one reply. Plenty of looks, just no replies.

I have a 2005 and need to replace the remote door fob. I see there is another one that offers remote start and a module for remote start. Is this a plug and play? Is the module a receiver that works with the existing wiring / computer? Do they come from the factory pre wired to accept this? Is there an RPO code that would ID this ?

I know, so many questions. . . .

I know there have to be similarities, they are both GM. Any help here?
