Question about Clarion Car Audio & Video
My Clarion model RT-9032C AM-FM receiver, installed as OEM in a 1987 Mazdda RX-7, has an inoperative on/off switch. If I can find a replacement switch, that would be great. If not, I'd like to find out what contact downstream of the switch should be powered when the switch is on, so I can introduce power to that contact with an external switch. Anyone have a wiring diagram for this unit?
It sounds like you're trying to introduce an external switch to the inside of the stereo, which would work I guess but it's a lot of work to crack open the stereo and locate the leads.
I think you'll find it far easier to go upstream of the power switch, and introduce an external switch to the power supply in to the radio -- as though the car was turned off.
To do this, just locate the red wire with the black stripe (or black wire with red stripe) on the back of the stereo and introduce your switch there.
If it comes in handy, here's the wiring guide for the rest of the stereo hookup:
