Anyone have a wire diagram from a 1994 GS300 LExus and know where to find a wire harness and dash kit for it. I attempted to use the factory deck bypassing the factory amp to two aftermarket amps, but I am having some serious issues. Help needed?

Is the Toyota 87 + the right harness for this car?

try your local circuit city, we have a ton of the gs 300 kits at my store, also its prob not the 87 and up toyota harness.  it is prob a harness with 4 rca's that integrates the amp, if i were you i would just bypass the amp all together and just hardwire everything.

Thanks!... that harness that you are talking about, is it the 70-8112. If so, is this the right harness to use an aftermarket deck and aftermarket amp.
