Default Switched 12v power source: hard wire radar detector

2011 Cayman S. I saw a Youtube video by "Cars+Raf" in which he used a splice downstream of the telephone fuse. I think it was a 10 amp, but appears to possibly be always hot. I need to try again with a 12 test light. All I had with me was a multimeter, and it was not my best one either.

I found the Tiptronic fuse position, and it is definitely switched power, but only has one terminal in it. I'd have to install a wire terminal for the downstream side if I want to use that position on the fuse block, so perhaps not.

What do you guys use for 12v switch power?

OK, follow up.

The "telephone" circuit is indeed not switched. I used the Tiptronic circuit because mine is a manual shift, and it's not like I'm ever going to add Tiptronic.

The fuse block is easy to remove with the now de rigueur plastic prybars and wedges. I looked at the back, and found that the fat solid orange wire is the one to use. I used the splice that comes with the "Valentine 1" hard wire kit. It was way too easy.

Now the radar detector comes on with the key, shuts off with the key, and I can leave it in the car.

The only drawback is when I remove the radar detector there is a wire hanging from the top windshield frame. The cleaner install would be to glue a connector block to the windshiled and make a custom coil cord out of telephone cord.

i used a fuse tap to wire in my radar detector and dash cam. i just tuck the wires under the head liner when not in use. you can't see it from the outside or inside. while i was at it i put a usb mni tuck in the headliner in case i need it later and wired another to the console for my phone.

If you can post a link to a picture of that setup, it'd be great. I noticed that the area around the center overhead light doesn't allow much room for wires and such, which is why I did not place the connector port inside the headliner. I used double stick tape to secure it on the driver's side body shell, underneath the fuse block shroud.

As an aside, the options list on my car lists 3 12v sockets. I can only find 2.

If it is a 981....

There is one in center console
One in glove box
One in passanger footwell on the wall behind the stereo (by left knee/foot)

Smoking package adds another at base of gear shifter instead of little spare change bin.

Well, I'll be dang. I never thought to look in the glove compartment.

As for what it is, I'm not as up to speed on 981, or 981.2 or what have you. All I know is that it's a '11 Cayman S with ABD ASR PASM ABS LOL

you have a 987-2
I don't know how to post a picture. The roof liner consist of the fabric and the plastic frame. the fabric is glued to the frame. but the frame will flex a bit for you to tuck the wire under. However, i put the transformer block and inline fuse (not necessary since i have a dedicated fuse for this in the fuse tap) behind the console and just ran wires up behind the A pillar cover and underneath the roof liner frame. my detector, an escort, only needed an rj25 jack which is small enough to fit.
btw i don't have a stock head liner. i had a local shop replaced it with alcantera when the porsche liner fell on my head. cars one quarter the cost of the cayman s have head liners that never fall on my head so porsche should be ashamed of its quality. i may have more flex because we had to take it all apart.

^ That is a very good description of my headliner. I actually like that woven cloth though. I'd probably keep the headliner or something similar. I pryed the overhead light out with plastic prybars, and found that the headliner snaps into the roof on either side. I used a zip tie to keep the radar detector cord in place, and act as a strain relief if the unit should ever fall.

As an aside, I don't like the way light "leaks" out from the front of the headliner when the dome light is turned on. It's worse than stock because I converted them all to LED lights. I'm thinking about cutting some foam and sticking it in the gap between the headliner and roof. The foam strip with adhesive backing that you can buy to weatherstrip doors will work perfectly here.

Definitely have only 2 12V sockets. None in the glove box. One in the center console, which looks to be standard, and one in the passenger footwell.

I have the universal audio interface, CDR 30, 235 watt sound package (not the Bose, and no subwoofer) and no nav system, etc. Pretty much no interior comfort items except for the radio with bluetooth.

Copy,

The glove box must only apply to 2013-2016.

As far if people talk about a 3rd plug specific to your year...on my 2007 911 it has one in the little door by the ebrake handle. If you do not have one there then you probably do not have the free option "smoking package" so therefore only 2 12v for you. Hope that helps.

That may be so. But looking at the order document that came with the car, the "Standard Equipment" column lists 3 12V outlets, and no smoking package.

The "Options" column lists stuff like sport seats, PASM, Sport Chrono, etc.

The "Exclusive Options" lists the spoilers etc.

So I would still believe that the car should have come with 3 sockets, but I can only find 2.

When I said that one was in the center console, I meant that it was in the little compartment with the long skinny lid with ash tray. Is that what you mean by smoking package? There is also a "Aux" input audio jack (not Apple). Maybe that resulted in deleting the 12V socket, but that is also listed in the Standard Equipment column next to "rack and pinion steering".

I decided to put thin corrugated flex conduit on the power cord to (1) clean up the look, and (2) keep the cord from having too much slack and vibration. Now I definitely can't tuck it into the headliner when the V1 is removed, but it looks much better. I decided that the light seepage at the front of the headliner is not a big issue, and I might want that gap anyway to tuck the cord into later.

The LED kit that I bought from Suncoast Porsche is excellent. They did not include an LED for the glove box, however. And I did notice that the LED on the rear trunk hatch is getting dim. Maybe a few of the diodes broke or something.

Well sir you have exhausted my knowledge so im not sure. The 3rd one in my similar generation 911 is in the center console under the armrest. The actual compartment NOT the long skinny area with ash tray.

However i do know you loose that outlet if you install this option from suncoast. SOOO maybe you lost one when they gave you the aux even though it is factory option.

^ That makes sense, which would mean that the factory installed "Aux" jack deleted the socket under the console lid. My aux jack option does not include the Apple iPhone jack, and is called "Universal Audio Interface". It only has the 3.5mm jack, which does not allow the volume and track selection to be controlled by the head unit, as does the iTunes one.

Also, the "speed activated rear spoiler" is listed. The dash button is still installed, even though the rear spoiler was replaced by the "Aerokit Cayman" fixed rear spoiler option.
