Hi Guys. Im simply looking for a diagram. year and model of vehicle are irrelevant as this is going on a customers house boat.

The customer has a sony marine head unit with an aux input. I am simply trying to setup his system so that he can use his sattelite radio, and his ipod off of the same aux input. Ive setup a relay with a 2 position toggle switch to break 2 different audio sources before, however, that was years ago, and have since then lost my diagram on how to do the setup.

Any input or diagrams would be very helpful! :)

DPDT relay

Din 72552 spec pinout
85- ground
86- control +

87- output to head unit +
87a- satellite +
87b- ipod +

88- output to head unit -
88a- satellite -
88b- ipod -

Note: 'Bosch' relays only use some of the spec, and I do not know the pinouts for their flavor of DPDT relays

Similar "boat"..car actually
I want to add an AUX to my factory radio.
I have the wiring and pinouts for the cable splices I need to make.

What I want to do is take this diagram: https://www.mbca.org/northtexas/audio_systems.htm and replace the switch with a relay. As the amplifier is AFTER the relay, it has to be a VERY quiet relay.

Can this be done?

Thanks
