Hey sorry I tried searching but to no avail for a 2003 or any 2nd gen.

I know how to hardwire a radar detector as I've done it on 2 of my other cars, but I just need direction on tapping into the correct wire on my 03 so it turns on only when the cars turns on. Any help will be appreciated. Thanks in advance!

 

Just use an add a fuse I did mine off of a window so i could toggle the window switch on and off to turn off my valentine v1 its simple

 

Never did it this way.. Any instructional available on it?

 

Add a Fuse to the Dashboard Fuse and Done Its the same fuse we use for the Fog Light mod 2.0

 

I must have done mine different that everyone else... I just tapped into the wires that ran to the left/right overhead lights where the home-link and sun glass holder are (it has a connector you can just jam the wires into and reconnect), then ran the RJ11 plug through the hole where the rear-view windows gets its power. Then again, I like my detector just below the rear-view mirror. No cutting/splicing necessary - just sacrificed a phone cord.

In later years I ripped apart a car USB charger and also stuck that in the roof with it also to supply 5V to a dash camera.

 

Second the "Add-a-fuse" technique. ran phone cord down the A pillar to the fuse box and connected to an existing fuse.
