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.

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

Isn’t the fuse box itself grounded?   When I did this I don’t recall a separate ground wire.  Ran telephone wire from fuse pigtail up A pillar to over rear view mirror and plugged in to V1 at left of rear-view mirror. I recall a good post on this with good pics.  Sorry I don’t have a better recollection.  Also wired a phone plug for use with remote display mounted on batwing where seat heater switches would have been.

I have a 2004 GT3 in which I'm trying to hard wire radar detector to the heated seats fuse.  There is a lot of plastic around the fuse box, where do you find a good ground?

Thanks,

 

The dash has several grounding points, just follow any solid brown wire and you will find one.
