What are you trying to do? Does the radio or the speakers say JBL anywhere on either?

i can't locate a wiring diagram for 1995-1997 with an amplified system but from what I can tell the 1998 unamplified is the same as the 1995 but without the power antenna circuit. Pins 8 & 9 on a 1995 vehicle, BLACK/ red & red, respectively, are used to power the antenna motor & relay. I would suspect that the amplified system would be similar for both years with the exception of the power antenna circuit.

Link to 1998 wiring diagram

This should point you in the right direction, where you can use a meter to verify your needed wires.

i would say that would be the red wire that is labeled amp in the diagram is the amp turn on.
test it, before you use it, it should go +12v with the radio on

Most amped Toyotas, Supra, Previa not MR2 have a spare loom adjacent to the original, plug in there to bypass the amp.
Those colours are speaker outputs and they maybe at the amp.
As far as I know and my experience goes back to the mid 80s, Toyota have NEVER changed those colours with the exception of some Lexus and the MR2.
