so i have this 1985 Corolla GTS...the owner before me had a Black top motor in it and i'm pretty sure he changed out the harness cause most wire coloring don't match up to most diagrams. i've searched google to see what car these radio wires and connectors correspond to. here is a layout of the connectors....The bigger connector is a 9 pin Blue connector and the small connector is a 5 pin Black connector.
BLUE CONNECTOR
[_R__][B/W]____[BLU/B][_____]
[ B/R ][_W_][W/B][____][ GRN ]


BLACK CONNECTOR
[_R__]_____[B/W]
[B/R ][W/R][_W__]



R--Red
B--Black
W--White
BLU--Blue
GRN--Green
[_____]--Blank no pins or wires on these
I used the Aftermarket radio install kit wires and none of the wires match up at all...any input will be greatly appreciated. Thanks

The link below is one I used to find out the free OEM stereo I was given came from a 1992-1995 Toyota Camry.

Good luck my friend. I am loving the oem amplifier too. Just need to buy better speakers and the same gauge wire.

When I did my raio I used this:

I did mine on Crutchfield.com and they gave me all the adapters for free, when i bought the deck and speakers
