2004-2009 Toyota Prius Quick Tip For Stereo Replacement.

If you are going to be taking on the task of replacing your car stereo in your 2004-2009 Toyota Prius, or maybe you are going to be installing an aftermarket car stereo for a customer in their 2004-2009 Prius. This is something you are gonna want to note. I have had several people contact me about problems they were having with their A/C controls, after they had their OEM car stereo replaced with an aftermarket one. This problem will occur if you do not use a 68ohm resistor to connect two wires in the 20 pin white harness removed from the OEM stereo. Just locate the white 20 pin harness behind the stereo, there will be two smaller gauge wires in pin 9 and 10. The wire in pin 9 should be a "Pink" wire, and the wire in pin 10 should be a "White" wire, get a 68ohm/1amp resistor. Strip back the insulation on both the Pink/White wires about 1/4in. and connect one side of the resistor to the "Pink" wire, and connect the other side of the resistor to the "White" wire. After you solder the connections cover and insulate with electrical tape. And that's it!

  1. Thanks so much for this info dont know what i would have done without it.

  2. Hey thanks for this Jeremy!

    One question: I am having a hard time finding the part that you describe as "68ohm/1amp resistor." Do you mean that I can get a 68 ohm resistor, or a 1 amp resistor?

    As I called a couple electronics supply stores I found that they have no idea what I'm talking about when I ask for a 68 ohm 1 amp resistor. The last sales representative said that they have resistors that are 68 ohm - 1 watt.

    Any advice?
