Ok, it was two green ones. I just finished my V1 with Stealth install. I'll create a new thread

2008 X5
 

The green/white wire worked like a champ! Used the torx for the ground - now my V1 is happy as can be!!
Thanks for those awesome instructions X5Mod!!!
Took me 5 minutes to pull back the overhead light module, used my fingers to pry it from the front (it hinges at the rear).
Just slipped a thin black rj11 wire through the front against the windshield to the v1.
Plenty of room up there for all of the components.

Thank you X5Mod
 

I picked up my new X5 35d on 12/18 and have been enjoying it very much. I have a Valentine hard-wired in my M5 and wanted to do the same with this car. Following the excellent description and pictures I was able to verify the switched green and white wire and easily installed the Valentine. The only issue I had was getting a good connection with the blue, clip-on connector. The wire was too small a gauge to allow the metal portion to make a good connection apparently. I took the blue connector off and crimped the metal portion that slips onto the green / white wire, re-attached the clip on connector and everything worked fine after that. :thumbup:
Thank you again X5Mod

Just hardwired a Belltronic X65 to the cigarette lighter. Just pulled the two panels as described in a different thread (do your search) and I was done in 45 min or so. Got the hard wiring kit with the smart switch for 24.99.

I know old thread is old, but I wanted to say thanks for the DIY on page 5. I installed my passport 9500 using the method described with no issues.

I did my Valentine V1 that way too.

Just did my Beltronics - great writeup and pics - thanks!

If you don't want to cut your interior like Xmod did, just fish the cable between the front windshield and the headliner. Yes there is like 4 more inches of cord showing but you don't have to cut your interior. I have did this the last 4 BMW's

Totally agree. I don't know why people do any cutting. Just push it through between the windshield and the headliner.

The cutting is almost impossible to see (as it faces the windshield), and it allows you to push the extra cord back up into the console when you aren't using the detector.
