12VDC cigarette lighter in 2005 Legacy 2.5i

[eljainc]

I have had my Legacy 2005 2.5i for about a year now. It's a great
vehicle. One of my
gripes is the DC 12VDC lighter power outlets. When ever the ignition is
turned off on
the car, there is no voltage available on these two outlets. I would
like to leave my
cell phone charging in the car for an hour or two sometimes, but can't
because of this
fact. Is there any way to get the cigarette lighters to remain active
once the ignition
is turned off on the car? From what I have read, this is a safety
issue. However,
I don't see the big deal in just using it to charge a cell phone. I
think one would have to
bypass the electrical system, or run an independent wire from the
battery or fusebox.
Any other ideas that don't involve me ripping apart the dash?

Greetings,

I believe that I would leave the system alone. BUT, on a 2001 Forester
(the only wiring diagram that I have) shows that there are 2 "multiple power
sockets". The power comes from the positive on the battery to a 25 amp fuse
labeled "Multiple Power Socket Fuse Holder". From there power goes to a
relay. Red wire in on pin 3 and red wire out on pin 4. Then the red wire
continues to the sockets. Should be the center pins. The outer shell of the
socket is black wire which ties to ground, completing the circuit.

On the relay there is a green wire to pin 1. That is power to the coil in
the relay. Pin 2 is a black wire that ties into ground. That coil is dead
until the car's fuse #4 gets power. Key on or engine is running.

SO what you want is the coil to be picked up all the time, or in this case
the contacts to be closed. The easiest way to do this is to remove the relay
and bridge wire 3 and 4 (red wire in and red wire out). That way all of the
other loads on fuse #4 stay on/off with switch as designed. AND the only
real change is power to the power sockets all the time.

An alternate way to do this might be to leave the socket in and just
jumper/bridge the red wires on pins 3 and 4.

Hope that helps. If you need the 2001 schematics showing this, let me know
and I will get it to you...

That is all I can tell you about an older vehicle. I DO NOT have the
schematics for anything newer than 2001...
