       E350 radio mod

       I posted this on the BCRV forum in 2016. Lost to Tapatalk. I
       happen to have a backup so I would like to post it here again.
       I would like to be able to use the 2004 Ford radio without using
       the ignition key.
       I would sure like to know if other Fords around 2004 have their
       headlights on when the ignition is on ACC.
       I was amazed how easy it was to get that radio out of the dash!
       I'm surprised it hadn't jumped out on its own. Just a gentle pry
       to pull the plastic surround off and then grab the radio with
       two fingers and slide it out.
       All these wires! Only two provide power to the radio.  The
       yellow wire has 12 volts all the time. This power wire comes
       through a choke in a little black box, presumably to reduce
       engine noise. The red wire is powered up when the ignition is on
       or in ACC and its voltage enables the radio to be turned on. It
       draws a full amp through the yellow wire, for the amplifiers I
       suppose.

       I can get all the power for the radio from the yellow wire,
       eliminating the red one from the ignition.
       I noticed that the radio draws 300 mA from the yellow wire when
       the radio is turned off but the input from the red one is
       energized. Can't have that going all the time while camping or
       parking. Have to use an external switch to turn the 12 volts
       from the yellow wire to the red input to turn the radio on.

       Looks a bit crude but it works!

       Re: E350 dome light

       We had some electrical trouble with our E350 class C.  The dome
       cab light stayed on all night and day, meaning a boost needed to
       start the engine. I’ve been disconnecting the battery overnight
       to prevent current running down the engine battery.
       Yesterday, we found a better fix.  That light goes on when the
       driver’s door is opened.  The switch looks like a black button
       sticking out like a ballpoint pen.  It needs a squirt of
       penetrating oil.  And leave the headlight knob turned completely
       anti-clockwise.  If you need the dome light turn it clockwise.
       Better yet replace the power eating bulb with a LED.
       There is another switch on the passenger door. I will need oil,
       too.
