Valentine 1 Hardwire
Installation Procedure

 

This procedure is one that I got sometime back on the web from several different sources. I've added my "two cents worth" where it applies to how I did my install. This was performed on a '98 M3 Sedan. Thanks go to Ron Stygar and Richard Biscevic for the "meat" of this procedure.

These instructions will position the radar on the driver's side by the rear view mirror. The unit hardwires into a 'switched' 12 volt power source, so that the radar will turn on and off with the ignition. I did not use an inline fuse, instead opting to use the fuse governing the overhead light. You may want to run an inline fuse.

This install will allow you to convert back easily or totally conceal the cord. The only drawback I've found is that my sunshade blocks the V-1 when down. However, the length of the power cable will allow you to adjust the positioning of the V-1 to your own taste, and will alleviate this problem.

Parts/Supplies:

  • Valentine 1
  • (2) Wiretaps (I got mine at Radio Shack)
  • 18" of telephone cord (the power cord for the Valentine)
  • A pair of pliers

Remove the header panel with the sunroof switch on it. The panel has hard plastic tabs facing the rear, so you'll want to bend the panel down slightly from the middle of the side facing the door. Work the back off first, rotating around to the front edge. It pops off pretty easy and doesn't require much bending. Disconnect the sunroof switch to get the panel out of the way.

Remove the overhead light from its housing. This is the one with the three-position switch that's in front of the panel you just removed. There are two metal clips on the side facing you that hold the overhead light in place. Push the interior light out by pushing in on the two metal clips.

Take the straight power cable that came with the (V1) and hold the connectors side by side with the locking tabs up. Look closely and you will see that the color sequence left to right is yellow, green, red, and black on one and black, red, green, and yellow on the other. Cut the cord to a length of 12"-18". If you use the later sequence, red will be +12V and green will be ground. If you use the former sequence, green will be +12V and red will be ground. I chose the latter sequence. When plugged into the detector the red wire will be toward the rear of the detector. In this case red will be +12V and green will be ground.

Pull down the driver’s side sunshade. You'll see the vanity light. Ease the vanity light out enough to run the end of the power cord without the clip, straight across to the interior light assembly. This is where you'll make your connection. Leave enough of the "clipped" end of the power cord out to where you'll mount the V-1.

Connect the power and ground wires of the Valentine power cord to the wiring going into the light assembly. The wires to connect the power cord to are as follows:

HOT = Purple w/ white stripe.
GROUND = Solid Brown (NO stripes).

Plug the power cable into V-1. Make sure no exposed metal parts are touching any other and turn the ignition to 'on'. Turn on the V-1 and make sure it powers up. If the unit does not power up, check all wires then review the Valentine manual. NOTE: The V-1 power cord wires are extremely thin. I had to strip enough wire to double it over itself to have enough to bite and hold in the wiretaps. If it doesn't work initially, check this first!

If the unit does turn on, proceed.

Replace the interior light the same way you removed it, and arrange any excess wire so that it can easily pull out for mounting adjustment.

Replace the sunroof switch and panel.

Push the vanity light back in and run the power cord around where the sunshade is held in place. This positions it perfectly for plugging into the V-1. Raise the sunshade to hide the power cord. Mount and plug in the V-1.


You're done. It took me less than an hour and would have been quicker if I knew to double the power cord wire to get a good connection.

Good Luck
