2001 RX300 Audio Pin connection 2/3 (CD Changer Connector)

 

2001 RX300 Audio Pin connection 3/3 (Amplifier Connectors)

 

Thanks a bunch. Do you have the pinouts of the multi display?? How about the radio circuit board itself?

 

Is there any mention of intermidiate connectors [cd to radio] harness?

There are no signal connection between CD Changer and Radio/tape Assembly.

Only TX (Serial Transmit for control - TX+ / TX-) connections are exist between CD changer and instrument panel.

Except 2 connections (TX+, TX-), all wiring of CD Changer go to Amplifier.

Amplifier gets two sound signals from Headunit and CD Changer. Also there are another TX to Amplifier from Instrument Panel. It control the amplfier with instrument panel so amp can select the sound source.

Thanks.

 

Amp is a module next to the radio and not the sub. right. I assume the volume, balance, fade, bass and treble control are part of the amp ... although from outside they seem to be on the radio/casette unit.

Any one has the insight as to which connector is easy to reach ... one behind the cd or one on the amp .... cd <-> amp.

Instrument Panel Pinout

 

Multi Display Pinout

 

Does anyone have pinout for an 1999 model?

There are 2 blue (10 pin, 6 pin) and 1 white (7pin) connector

Thank

 

If i was to go with a stronger amp, should i keep this amp and hook only the speaker wires to a new amp, thereby keeping all the other connections intact????
