Hello. I'm watching "JVC-Kenwood." The diagram has resistance and TR. But I don't know the part number. I'd like to know the part number.

-Note - My car has three lines: SW1, SW2, and SWG. The HU(keywood DMX9706S) has only one SWC line. I think this project is right, so I'm going to try it.

The parts I used are as follows.

Resistance 1 - 3.3kohm Resistance 2 - 10kohm Resistance 3 - 120ohm Transister - NPN(2N3904)

I haven't made it work yet.
