Is there an afermarket or OEM alarm system that can be installed to the g's that existed prior to TPMS being available?

Thanks

Not sure I understand the question. TPMS was available on 04+ but I don't understand the relation between tire pressure and the alarm system on the 03?

There are 2 pieces to the TPMS system. The sensors and the receiver in the car. I have seen it called 'alarm' before. Not to be confused with the Cars passive alarm system.

I also have a first series release of the '03 coupe, but I don't think any 03's had TPMS.

I am curious if you can add it. I have the sensors, but nothing that communicates with the sensor in the car.

I understand now. You can do a search again but I don't think anyone has modded a receiver/sensor alarm to the 03. I've seen it discussed a couple of times but no positive results. Someone else may chime in and give a better answer.

I couldn't find anything in my first search so I am just going to drop it. It is not a big deal. Thanks for your replies!
