996.2 radar detector hardwire

Recommended Posts


trying to hardwire a radar detector to an 02 996 c2. fuse panel slot D8 (radio) looks like a good candidate for the add-a-circuit, but i dont have access to a multimeter to determine the load and draw sides. is anyone familiar with which side is load and which is draw?


Here is a photo of the fuse panel. i just need to know if A or B side is load



And here is the add-a-circuit i am using. some say pigtail side up, others say pigtail side down.

Do you have heated seats?  If not, add circuit to seat heater fuse location.  This is an un-switched fuse that is powered when engine is running.

lots of info on forum.  Search engine will be your friend.

Use the factory cell phone spare plug located behind the center console (CD compartment). The plug offers switched and unstitched 12V.


Brown = Ground 

Red / Green = Switched 12 volts 

Green / Black = Unswitched 12 volts 

Yellow / Black = Telephone Mute
