So I've successfully taken out the stock radio, and put my new pioneer double-din FH-X720BT in its bracket. I tried testing it out and the stereo powers on, but theres no sound. I have the ground, battery, and ignition all wired up. (red, yellow, and black wires) I can't figure out where the rest are supposed to connect to. There is a blue/white cable on the wiring harness which is the amplifier turn on, which im assuming needs to be connected, but there is no blue/white wire on the aftermarket stereo except for the antenna. Could someone please help me figure this out?

The top image is the harness and the aftermarket plug-in. (harness on the left, aftermarket plug-in on right)

Bump. Response does anyone know what wires hook up to where?? Has anyone done a diy stereo install on a 97-2001 ES300 that can help me please?

Did you plug in the RCA's as directed?

The Blu/wht, is unecessary. That is for an aftermarket amp, and system if you ever add one.

I noticed the Blue isn't tied to anything? IIRC, that one has to be wired up with the power antenna on from the HU as well. This is like a secondary signal for the deck to know when to run the radio, otherwise it won't turn on that function. I had no radio recently when re-doing an old subwoofer install on my current subaru and trying to use that as the signal wire since the amp turn on is only 5v.

All I can recall was actually wiring up the RCA's and 5-6 of those individual wires. The Blk/Red/Ylw/blu/orange for the illumination. That was all I needed to do, I'm fairly certain.

BTW, you're going to need ground loop isolators. I used one of these since it was a two-in-one and made nicely to tuck away under my deck; http://www.monoprice.com/Product?c_i...seq=1&format=2

As opposed to, two separate giant ones.

Good luck!
