996.2 radar detector hardwire

[Eștii]

 

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.

No I dont have heated seats. I searched around and found instructions for 997’s but not 996.2’s

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

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,

I routed my ground wire to the right, under the footwell across to a bolt near the shifter. Its kind of a long way but thats the only metal to metal location I could find.

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.

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