After being re-installed, my stock honda radio is dead. No signs of life.
Any ideas?

Here's the actual story:

I had an aftermarket radio put in long time ago, but since the keyless entry
is built into the stock radio, the installer put in a special harness that
allowed the original stereo to stay connected and powered behind the dash.
Everything worked fine untill a few days ago someone broke into my car and
stole the aftermarket radio (sucks, but that's life)

They took the radio and cut the wires where they connected to the splitter
harness (why not just unplug them is beyond me, but...). The harness was
left intact and they left the stock stereo. However after that the remote
stopped working. So I figure untill I get a replacement deck, I would use
the stock radio. However after I got it out from behind the dash and
installed it proper, it is dead -no lights, no nothing.

I checked the fuses, they seem to be fine. Checked voltage on the harness,
there is 4.3v on the backup lead all the time and about 12v on ACC when the
car is on . Sounds like power is ok.

I thought maybe they shorted something out when they cut the cables, but I
looked at the radio and there seems to be no visible signs of damage.

I figured maybe it's the security code issue, but from a quick search it
seems that when it wants the code, it powers on and asks for it - so it is
probably not that.

I am at a loss. Any ideas?

I am thinking of giving up and getting a new deck and an alarm system that
has it's own keyless entry in it, but I would prefer to keep the costs down,
money is definately an object.

Also, there are 3 harnesses in the back, one is radio (speakers+power) one
is "security" (I assume this is keyless entry and stuff. What is the third
one? Also, is there a site that lists pinouts for those harnesses?

Thanks a bunch,
