I searched all over and found no evidence of a factory stereo harness for my 99 gs300? I find it hard to believe that all the 2nd gen gs's didn't create enough demand for some company to make them! I bought a harness for a toyota avalon thinking the wires would be the same, and of course they weren't. I really don't want to cut my factory harness. Can anyone at least point me towards a wiring diagram for the 2nd gen gs?

Thanks

 

brother u are s.o.l.. how ever there is a solution. explain to me what are you trying to do? and i will provide you the needed 411. this is what i do for a living. not beign cocky but i got a serious system on my gs and im still able to go all factory after all the custom goodies i did. so let me know. always at your service!!!

 

I'm just trying to put in my new deck (pioneer deh-p9600), but i cant get a wiring harness that plugs into the existing factory wiring. I just don't want to have to cut and hardwire, you know what i mean? I would rather have someone make me a custom one or modify my existing avalon harness (it plugs in, but the wires are in the wrong places on terminals)

 

You have to wire out the factory amplifier that is behind the glove box on the passenger side.

Can someone tell me which one i need?

 

Come one, someone has had to have put an aftermarket cd in their gs. What did you do?
