1995 avalon factory stereo

Hello, i'm not sure if anyone can help me on this since i have not been able to find ANYTHING on the web that has helped me yet but here goes:



I am helping a friend of mine with installing a after market head unit and subs in his 1995 avalon. after buying a wiring harness (1989-2001 toyota..package even says 1995 avalon) and removing the dash and factory head unit, we find that in no way will this harness work. so we search the web and cannot find a single wiring harness that looks like it would connect to his factory harness. as far as i know he has only the factory cassette player/am/fm radio, no factory amp.



so we decided to hard wire to the factory wiring. once again we searched the web for any type of wiring diagram/information as to what wires go where... all we found was wiring for the factory amp...light green, pink, light blue, and other colors that in no way match the factory wires in his car (blues, whites, a red, blacks, greens, yellow, black with red stripe, and can't remember others off top of my head...14/15 total) . If anyone could give me any information that differs from what i've found already, it would greatly help. Thanks.

As you have noticed, Toyota does not use standard wiring colors. Check the links below for wiring info on the Camry. Should be pretty close.

That harness will not work because there is no harness for that year Avalon. Since all stereos offered in the Avalon used an external amplifier, Toyota did not include the set of wires that the harness would plug into. To do a proper job, you will have to remove the glovebox and splice into the wires on the output side of the factory amp. I would not recommend using the factory wires that run from the head unit to the amp since they are of a very high gauge and cannot carry much current.



Just an FYI, the factory amp is a 42.5 watt/channel (170 total) jobber, which is less than most aftermarket headunits. I believe the plugs are blue and green, but its been 3 years since I did the job on my Mom's Avalon so I may be wrong on the colors.

I did this on my 97, pics and a color chart and all. Just look through the threads here and you will be enlightened.

I just did my 95 and the info that sickwilly provided made it easy. The only problem I ran into was getting the power antenna to work. After looking at the wiring diagram in the haynes manual I realized there are two wires that have to be connected to the head units antenna wire.

I only connected 1. I get great reception on the FM, but bad on the AM. Could this have anything to do with it?

I'm not talking about the antenna signal coaxial cable, I'm saying that I had to connect the blue wire from the radio to two other wires to get the power antenna to go up and down.

So you would just unplug the blue and green connectors that go to and from the amp, cut those connectors off and splice by color to bypass the factory amplifier?
