Hi all,

I need some info on a 2003 Chevy S-series Blazer. Really just need to know if it has the Passlock II, or anything else that's different than 2000 models. I did a keyless on this truck a few months ago, so I've got that info. Swapping out for a Remote start/keyless entry on Saturday morning. All help is appreciated.

The blazer will have Passlock II. I don't think there is really much at all different from the 2000. 2 ignitions, 2 accessories (brown shouldn't be needed), 1 starter, etc.. Locks are white and blue positive at the bottom of the fuse panel on the left side of the driver underdash. You can also pickup your park lights (light blue pos), hatch pop (BLACK/ white pos), and I think brake (light blue pos) there as well. That hatch pop can also be grabbed at the switch on the dash (black neg). OEM disarm would be light green (-) in the drivers kick/boot area. They all have the underdash light which will cover all your doors. Horn is black (-). Easy install.. Good luck,

Mike
