Installing a Touch Bluetooth Module with Single Channel Relay Switching Circuit Pioneer TP900

Installing a Touch Bluetooth Module with Single Channel Relay Switching Circuit to All Stock Pioneer TP900 Vintage Car Stereo.

On this video I will show how I installed a touch Bluetooth module with single channel relay switching circuit on my all stock TP900.

Modification on the TP900 is very minimal.

Power supply for the switching circuit module is from the white wire 12v supply of the tuner board.

The ground for the relay modules are grounded to the chassis.

The audio wires from the Bluetooth module are connected to the pre-amp board adjacent to the orange wires.

Cutting or disconnecting the orange wires is not necessary.
Switching is all carried out on the power supply of the tuner board and Bluetooth module only.
If the tuner board is on, there is no power to the Bluetooth module.

If the Bluetooth is powered on, the tuner board power supply is cut-off, no FM signal.

No modification done on the TP 900 switches.

Please watch the video till the end, for detail.

Thank you
