94 toyota audio system help!!

======================================== I purchased an Alpine CDE-9843 from Crutchfield, and all the new connector wires matched the Toyota wire colors so the process was simplified - for a 1994 Camry. The unit works great. For the PDF file you posted, for 1987 and newer, looks to me like the column headings are reversed. The column on the right labeled "Typical New Radio Equivalent Wire Color" is actually the guide to the existing Toyota wire colors. For example "A" , the gray wire, for Toyota, is the Right Front Speaker Positive. "B" for Toyota, is White - the Left Front Speaker Positive. My diagram had slightly different wording for the power wires. Red is

12 volts Switched Power, Yellow is 12 volts constant power. Also, Blue from Toyota is power antenna, and it should join H and I in the new connector. On my new connector, there was already a wire loop connecting those pins and a single blue wire coming out to connect to the Blue Toyota power antenna wire. J, marked "do not use" on your diagram is marked "Orange/ White - Dimmer" on my diagram, and there was a connection for it on the new wiring harness. As far as I can tell, this wire operates the illumination for the new stereo unit. There's a note that says "If your receiver does not have a dimmer or illumination wire, tape off the Orange/White wire. Black is called "chassis ground" essentially the same as yours. My new radio also had the wire functions listed on a label/sticker on the bottom of the new unit. If your new unit has one of those stickers or labels I would go by that, and use the functions listed in the Right column of your PDF file as a guide. For example, the "Green" wire should be "Left Rear Speaker Positive" _not_ "Right Front Speaker Positive" and "White" goes to Left Front Speaker Positive, _not_ right rear speaker negative.
