Could someone explain, to a car AV newb, why I would need this over a standard wiring harness? I drive a 2003 Lexus IS300.

This is a wiring converter. You need it to plug your new stereo into the Lexus speaker system. It's designed specifically for the IS300. I used it in my 2002.

I have a 09 tacoma with jbl. will i need any other harneses or adapters to install a aftermarket radio?

that one is to start the amp. if you want to use your steering wheel control you will need this adapter xxess ASWC...

Did any one else have an issue with it jumping in and out volume wise?

It might depend upon which version you got and how you connected it. In the older versions, you would plug it into radio pre amplifier outputs. The wiring harness came with RCA plugs so you could easily just plug it in to the pre output. This had problems with the sound, like the one you mentioned, plus static issues, so they changed how to connect it. Now you connect it to the amplified speaker outputs. The wiring harness no longer has the RCA plugs, but wires with stripped ends to connect to the speaker wire outputs. The photo of this unit is of the old style with the RCA plugs. I don't think you can get it that way anymore.Note, in spite of what it the manual says, it does not work with all Toyotas and Lexus's. It works if you have a JBL radio. It does fully work on an RX330, which has a Pioneer radio. Almost all controls work, but the fader does not. The fading is permanently stuck at approximately 50/50.

Does it fit on Toyota corolla s 2010

If your corolla has a JBL system it will work
