I have a 1992 Toyota Camry, and the car was my mother's before it was
mine. About ... 2-3 years ago the radio went out one day will she was
driving. Anyway, last year I bought the car from me her, and have been
using portable radios for my music and news needs. But, a friend
recommended that I check the fuses just in case one of them is out, so
I do. I checked all of them that had to do with the radio, and non
were blown, so I changed them anyway (all of them, just so I know when
the last time fuses were put in). And now the radio still does not
work. The fuses I changed are the ones under the hood, and the ones on
the driver side, but to no avail. Does anyone have any suggestions?
Any help would be much appreciated.
It doesn't look like there is any power going to the radio. The dial
doesn't light, and the antenna doesn't go up. I press the power
button, and it just sits there. I found the EWD for the '91 models,
but not for the '92. They look almost identical in style, do you think
I could still use the '91 in the stead of the '92?
I don't know, but it won't hurt to try. Just track down the +12 volt
source from the battery to the radio. There might be an ignition cutoff
(burglar alarm) so you can't just jump the battery to the radio for
testing. Good luck.

Now Toyota's wiring is proprietary, so the colors are different. If you
have the manual page, it should list the connector and connections. Go get
a cheap V-O-M (volt meter) if you don't have one, if you can get one with
clips as well as regular leads; clip the black wire to something metal
attached to the frame of the car, and use the probe on the connector.
First, leave the carr OFF totally. You should find one connection that has
+12 volts on it. This is the 'Back-up' that holds the stations in memory.
Depending on who made the radio, it may or may not be needed for operation
(Radios were made by National (Panasonic), Fujitsu and Clarion. I believe
the Fujitsu needs the Back up operating...)
If you can't find +12V this way, this may be your problem. IIRC, you said
you checked the fuses; did you look under the hood? There is a 7.5A fuse
there that, IIRC controls this connection. If all this is good, turn the
key to ACC and check the connector again. You should now have TWO +12V
connections. If not, this is your problem.
If both these are good, you /may/ have a blown fuse inside the radio!
These can be a REAL pain, since they usually look like a green or blue
resistor and are usually soldered onto the circuit board. The CKT BDS are
CHEAP, and you can easily lift the pads trying to install a new fuse. I
have YEARS of soldering experience on NASA stuff, and these things STILL
throw me for a loop. I send them to United Radio (Toyota's Warranty Repair
Center) in Upstate NY; for a nominal fee they swap the radio out.
Good Luck! Let us know what you find!
BTW, I have had ONE toyota that had the original radio that did NOT go
bad; that was a 1974 Corolla 1200 I bought new with a Clarion AM/FM MONO
radio. On the rest of my cars, I have replaced the stock radio with
I have bought 4 used Toyotas in my life, and when I replaced the radio,
EVERY ONE of them had a sticker from United Radio on the radio, and a
warranty sticker missing from the warranty book!

These are the car's harness wires.

These are the cables that come out the back of the new radio I bought.
Now, how do I connect the two? Do I have to cut the wires and connect
them to their mate on the other?
Thanks much for pardoning my poor English.

I went to Wal*Mart and bought one of those connectors, because I *MAY*
want to swap the radio out of my Scion (What? A Scion with a STOCK radio?!?!)
But, I actually like the sound. Wal*MArt didn't have any of these
connectors (Model TA021) on their Web Site, so I wanted to get one before
So, looking at the picture "DSC0404.png", the connector on the LEFT we'll
call Connector 1, and the one above your thumb we'll call Connector 2, the
wiring goes like this:
On Connector 1:
(I Hope the pic isn't reversed; I'm looking at MY connector as if I were
going to plug it into YOUR connector...)
The Top Left pin is Purple. This is Right Rear +
Then there is a space, and then the keyway. The next pin, top right, is
Green. This is Left Rear +.
The bottom row, from the left: Purple/Black, Right Rear -
Bottom row, right Green/Black, Left Rear -
on Connector 2:
Starting from the left top:
Grey. This is Right Front +
White. This is Left Front +
Keyway, then blank
RED. This is +12 V from the ACC connection.
Yellow. This is the +12 V BATT connection, always 'ON'
Bottom Row from the left:
Grey/Black. This is Right Front -
White/Black. This is Left Front -
Black. This is GROUND
Blue. This is Power Antenna. This is an "As Needed" wire, or to turn on an
Blue. Also Power Antenna. This will provide the power through
the harness to the antenna.
Orange. Dimmer. This is what causes the radio lights to dim when the
parking/head lights are turned on.
Now, the stumper. The OTHER harness you're showing me from the radio does
NOT appear to be a Toyota harness! In looking at your picture, it looks
like someone spliced this connector onto the radio. They DID have one of
these at Wal*Mart, and it was marked "Generic Import Adapter", and was
listed for certain models of Nissan, Honda, Subaru, etc, but NOT for
Toyota. So, whoever you got this radio from must have had it in a
different car and 'lost' the original connector!
This is NOT good! It looks like 15-16 pins? The Toyota connector has 10
pins on one connector, and 5 on the other.
The only thing is, if the wires are EIA standard (Purple, green, white,
grey, red and yellow) then you can take the info I've given you and get
some push pins at an electronics store, crimp or solder them on and mate
them to yuour car's connector.
I'll take another look on Scosche's web site, they may have further info...
=============It is recommended you do not cut any original Toyota wires.
Ask crutchfield.com to send the correct wiring harness connector and
color codes for your model year.
Then you do all the splicing and soldering (or wire nuts) on wires that
are not part of the original wiring in the car.
