Hi,
      I posted a few days ago asking about a bypass switch to run the
driver's window on a 90 camry.  (A plastic part in the switch panel
broke and can't be fixed.)
    SMS was very helpful in pointing me to a DPDT momentary on-off-on
toggle switch.
    I got the switch (thru NAPA) and I understand the wiring setup
needed  for  the switch to  the window.  (Thanks again  SMS)
    What I'm not sure about is the ground and hot wire that I should
tap off from to connect to the 2 center terminals  on the switch.

    There are about 18-20 wires running between the door and the main
body of the car.  (Several were cracked/broken and have been
repaired.)
    As best as I can tell, the white wire with a black stripe is the
primary ground wire, but what is  the hot wire that I should  use?
     Is it the solid blue one?  
    I'm not very good electrically, but I used  a multimeter to  test
all the wires.  (I disconnected the white and blue plugs.)
I tested the car-side wires in both plugs, and several of them showed
voltage around 12.  The solid blue wire showed the highest voltage.

     If anyone  reading this is familiar with the wiring circuits for
the 90 camry, I would appreciate a  confirmation  (or a correction)
that I  should  feed off the solid blue wire for  hot current to  the
switch.
    (Am I also right that the white wire with black stripe is the
ground?)

    Thanks for any  help!

       I wish I knew  more about wiring.  And it would help if  I had
a diagram.

Hi Dave.

You are correct, the Blue wire is +12V, the white/black is Ground.
Are you aware that if you use the switch that you purchased, you'd
lose the "Auto Down" and the travel limits functions?, that switch
ass'y contains electronics that does more than just move the window up
and down.(I would try and get an original switch ass'y)
Did you try a junkyard?, Did you try an online Toyota dealer?(some of
them are much cheaper than your local Toyota dealer).
If you want a diagram of that system reply to:
yjrybano2spam@yahoo.com(remove  no2spam  from address).

Hi Jerry,
    Thanks for responding.  I appreciate  the confirmation.
I   went ahead a couple days ago and tried  wiring it up that way.
It worked.
    I'm only keeping the car till this fall, then junking it.  I just
wanted a  quick  and  cheap way to open the window during the
upcoming hot summer months. (The A/C broke a couple years ago.)
   This ended up costing me less than $10.
I didn't really care about the other functions  of the original
switch.

    Thanks  again for your time  and reply.  I appreciate it.
