HOW TO: hard wire radar detector (or any 12v device) to fuse box

ok here is the truth behind all this mystery. All you need is a universal DC jack (available at radio shack). Just tell radio shack your intentions and they can tell you the wire to buy. What you want is the small connector to your radar detector attached to a length of wire. Run this wire behind the molding to almost any 7.5A fuse in the fise box (use the positive end of the detector wire in the fise box). If you are buying the kit from best buy (not a bad choice) the positive is white and black (solid black is negative).

Pull out a fuse (I used the one for my radio; its labeled on the plastic panel that covers the fuse panel) that is 7.5A. You could use the one for your dome light, etc. It doesnt matter if you don't mind turning the detector off as you leave your car. If you care about turning it on and off, use the one for the radio as labeled. (It IS different for different years).

After connecting the positive here simply by folding it over one of the fuse metal connectors and replacing the fuse, now you need to connect the negative. (BTW, there is a fuse key to remove fuses located under the hood in the fuse box. This is mounted to the firewall on the driver's side in my 2003 ZX3).

Now, just remove and of the screw that hold the fuse box in place on the chassey and screw down the negative wire here. You really could just tape it to the chassey if you wanted, but that is not nearly as permanent or secure as it could slip out.

Now, connect the radar detector and you're done! Remeber, you just need 12v DC, it doesnt matter the source so just pick any you'd like.

Feel free to ask any questions!

also you can just cut your cig lighter plug off, mine broke so i cut it off to add a new one, then thought well why don't i hard wire it. i had it on all the time, doesn't run down the battery but i would recommend wiring to the radio. but yea works great, frees up the cig lighter for my phone charger

In will post pics this evening after I take a few. The fuse number that I used on my 2003 ZX3 was number 41 by the way. That way when I kill battery power to the car I also kill it to the radar detector. Otherwise, the detector has to be manually turned off to avoid battery drainage. oh! This guy does a good job illustrating the project with pics.

(Thanks to whoever made that site)

The only thing I might add is that you don't actually need to have the "adapter" he talks about for the fuse box. You DO need the appropriate connector for the detector (i.e. the $11 kit they sell at bestbuy) but it suffices to use duct tape or electrical tape to hold the wire onto the selected fuse.

Allow me to clarify one thing, the size of the fuse chosen in the fuse box doesnt matter all that much. Most likely there will be a second fuse on the positive "hot" line leading to your detector. So if there is too much current that fuse will just blow. If you have personal questions regarding this please send me a PM and I will try my best. Thanks!

^^^ Correct.

I did this mod 2 years ago and it was kind of annoying to turn off the radar detect manually.
It's nice to have it turn off when you kill the ignition key.

I know this thread has probably been long over butttt..... I have an 06 and I dont have the "would be" moon roof control area - like its all just "carpet" (if thats appropriate for the ceiling). I just wanna know if anyone has any suggestions how to take the lamp off in the 06. I cant seem to find any screws or anything.

I have an 06 too, took me a while to figure out how to get the lamp out, but its pretty easy once I got it.

-Shove your fingers up between the grey molding and the headliner.
-Feel for the clear plastic part of the light.
-Push down on it, it should pop right out.
-Remove the two screws holding the grey molding piece to the roof.

Heres how I ran the wire for my radar detector.

I'm trying to hook up my MP3 player/GPS (Mio C310x) so that I don't have to use the cigarette lighter ('cause it looks like poo) and route the audio through the stereo (no freakin' FM modulators - hate 'em). This post has helped me get the first half figured out. Gotta be honest, though, the pics weren't all that great - I'll try to get some when I perform the mod.
