the reason for this is because of the 'concealed display unit'. It
re-routes power to itself and disables the display on the main unit.
I don't know the electronics behind it, but that's why they use the
data/phone cable instead of cheaper 2 wire cable

Now THIS is nice to know. I'm not too knowledgeable when it comes to
playing with car wiring, and I wouldn't put it past myself to screw
something up if I took on a major project.
I also used the direct wire adapter so my V1 is now switched with the
ignition. We wired it so it feeds power from one of the power wires to
the radio. Unfortunately, neither I nor my friend who did the actual
wiring remembered that my radio dims the display when the headlights are
turned on or off, and this change is enough to interrupt curent to the
detector, essentially shutting it off momentarily...enough to reset it
to the 'A' (All Bogeys) mode. So just remember to tap into a current
that is only affected by the ignition switch if you use the adapter.
