*EDIT* Please see page 5 of this thread for an alternative wiring option AND how to mount the stereo to the factory stereo bracket assembly! I've also added the Metra stereo installation pdf as an attachment for those interested in the resistor modification in case you don't want to use an additional wiring harness like I did. Or watch the videos below... I thought some might like to see the pics of my latest mod. The install is a breeze and uses the factory ISO mounting hardware. This makes for a solid mounting base and makes it near impossible to steal! The only aftermarket pieces required are a standard Toyota BHA-1761 wire harness and a single 68 ohm resistor. The alternative, and preferred method, is to use the BHA-1761 (OEM to Aftermarket) harness and the BHO-1761 harness (OEM to OEM). You MUST use one of the two methods in order to eliminate the dreaded orange triangle or MFD errors regarding the AC system. In my original install I used the first method and while everything worked fine, I was not happy with the install so I switched to the second method and it is the one I recommend. There was no cutting, bending or and amount of "custom" work done during this install if you don't count the resistor. With the cover open. Cover closed (this is how bright it looks at night) It is MUCH dimmer than if I drove with the cover open. cover closed (I included this pic because I forgot to take a pic with the stereo off so you could see how well it is hidden) One could easily add some window tint to the inside of the cover to make it even darker and thus more stealthy. This "How To" slideshow created by Jeffvk clearly demonstrates how to connect the 3 wiring harness together properly. His project was the result of a "magic penny" being fed to his OEM stereo. 2004-2009 Prius Stereo Install "How To" - YouTube See photo attachments below to see what the wiring harnesses should look like when making connections: Install videos. These videos take you through the whole process of taking the dash apart and installing the stereo. The wiring shots are not very clear so please refer to the Magic Penny video above.
