I have an '03 SE w/ rear air.

I want to add the back up alarm that comes standard on the HSE...does anyone know if it is pre-wired or how difficult it would be?

My sweetie pie is 4'10" so this is a very necessary investment.

 

It should just hook up to the reverse light and ground.

 

I am not sure, you might aught to call the service manager at your dealership and see what he says.

Service manager said $800 in parts plus labor to program the computer to work with the back up alarm.

Stand Alone systems are out there for ~$50.

I did find an unused plug behind the rear bumper on the driver's (left) side. Any idea what that is?
