New stereo, alarm problem
 

I installed a new stereo system in my wife's 2000 Boxster for Christmas, but the alarm beeps when I lock the doors and it goes off randomly. Anyone know which colored wire I need to connect to what to stop this from happening?

On my 99, the ground wire connects to the radio chassis. It is on the left with a female spade connector. The male spade connector is on the metal surround also on the left. I think the color is black/green, but I wouldn't swear to that. It's short. Only about 4~6 inches is accessible.

Look at the head unit you removed. You will see that there is a sticker on one side of it. (I think it is on the left.) If you put a piece of duct tape in the same position on your new head unit, that may solve the problem.

Good luck.

Here's a picture from an 01 wiring diagram. The alarm contact wiire is on the far right. It's brown / blue. Hope this helps.

Just to update the post, this was it. I found the frame for the new stereo was touching the ground sensor on the left side of the unit. I put some electrical tape on that area to break the contact and also put some on the head unit in the same area just in case. Since then there is no problem with the alarm going off.

Thanks! :cheers:
