thank you but i already tried that.
i have wires that are..blue w / YELLOW stripe and grey dots about an inch apart..(just to give an example) coming out of the car.

This car has a factory amplifier that needs to be bypassed when installing a new HU. The amp is most probably located behind the glove box on the right hand side. It is a silver box with two plugs going into it. These plugs are the same as a Toyota aftermarket harness. Get one of those and extend the wires to the dash and hook up your new radio. On some models, the factory amp is under the passenger seat. ALWAYS test all wires with a Digital meter before any install.

im trying to replace the stolen HU with my factory one but my wires have been cut so i have no idea what wire goes where. i found plugs off of an older gs..it fits physically but the wires are not the same colors for me to line up.

Unless you have tested them already, I would test the wires in the car as per the diagram that DYohn has posted for you, I dont think that the grey dots make a difference, as long as you do have the same colors as the diagram. Also what year GS did the new HU come out of?? Try using the diagram on this website for that year also, and combine the two. -------------

hi.
it is from the 2000 just like my car. how do i checked the wires? can i just run an amp from the stock HU or would i have to run it from the stock amp? thanks.

If I were you...I'd make a trip to the local Lexas/Toyota dealership and ask for a wiring schematic for the car. They may charge you for it but it'll be worth it. ------------- Duane...
If you think you're confused, imagine how you feel.
