For the life of me, I cannot locate a +12VDC line beneath the drivers side where the steering linkage is located. PLenty of wires, but I'll be damned if I could fine +12VDC switched.

Has anyone had experience with a 08 CTS4 DI and hard wiring a RD (radar detector)? Should I look at the passengers side under the dash?:confused:

I'm not looking to go through the overhead console or the rear view mirror since I think that would make it more difficult to run/hide the wire to the indicator/mute control. I'll be looking for that brown +12VDC switched that ngiradina spoke of.

If it all comes out, I'll post picks where to find the wire and how to route.

Geeze. This shouldn't be difficult for a guy who retired from the Navy as a electronics technician. But then again, who wants to screw up their own car.

My advice is directly from techservices.audiovox.com, which thus far for me, has been perfect. Your only other option that I can think of is to run a fused power wire from the switched side of the underhood fuse box, or to add a fuse to the interior fusebox where the cigarette lighter would hook up.

OK. I had the RD set up in the top left corner of the window with the direct wire cord all nicely tucked away into the pillar and down the door weather stripping with a quick u-turn into the area where the emergency brake peddle sits. I got the ground attached in behind the screw that secures the OBDII connector to the car. No problems there.

Once I started looking for the +12VDC, I just didn't seem to find anything, but then again, I didn't break any of the wiring harnesses open since I need to get some electrical tape.

If you're pretty confident that it's brown, I'll give another look. I was thinking about looking on the passenger side too.

Don't work harder, work smarter. The installer that would have charged you $200 to install your radar detector would do the same. If I'm wrong, it will only cost you a fuse, and if I'm right, it will save you hours.

ngiardina. Man, all I am finding is 15 VDC! Even in the fuse box where there's spare ports...all read 15VDC

On a good 12v system, you should read from 13 to 15 volts. Go for it, you found the wire.
Oh for pete's sake. You have to be kidding me! I was thinking that, but I was afraid of any possibility of frying the RD. Thanks again.

Don't know about the CTS, but on my wife's STS, the freakin' fuse block is under the back seat. I had to pull the seat to use an Add-a-Circuit to hook up an Escort, then run a wire under the edge of the sill plates to the front seat area.

Not hard really, just amazing that they hide the fuse block under the back seat! Imagine trying to troubleshoot a fried fuse on a cold, dark night on the side of the road or in a parking lot. Geez - make it a little easier! :thepan:

So was the install good? What voltage did you need for your detector? Yea, that seems like a very inconvenient place for a fuse block.

Is there any good way(point) to connect a wire(new line) from the front 12V remote port to inside?
And, is the front remote 12V box alway on?

I thought your next post would be more along the lines of "Woo-Hoo!, It works!!!"
Oh yea, that post is coming but I'm absolutely exhausted for the day. Hopefully the weather cooperates tomorrow so I can try it again. I'll try and take pics of the process.
