  • e46, Rear-View, Relay... suggestions to relay...

    So I've had this rear-view mounted in my keyhole for over a year now. I hooked it up to my reverse lights to get power, thinking that would do the trick.

    Well it sorta did -- though from what I recall, the power to the backup lights are intermittent, and not a solid source of power... which works to some degree, but the picture is almost fuzzy at best...

    Again from what I recall I need to have a power relay switch that will let me have a power supply of clean power, but get triggered from something like the reverse lights going on.

    Any suggestions or threads that you're aware of that I couldn't find that may help me out?

    Thanks everyone!

    Ok, so I stumbled upon a page that gives a huge walkthrough (overkill for what I'm wanting) of integrating tv/rear-view into a 7 series... but the takeaway here for me is the mention of the relay switch

    (if interested )

    They mention a 'Standard Automotive Relay" ... with a picture!

    Any recommendations for a particular relay such as this?

      Intermittent power to backup light!?? Are you sure? If so, a relay will not help you.

      Have you connected to the right wire?

      One thing that might cause a problem is the "lamp fault detection". In that case the relay might help. I am sure any car relay on the nearest gas station will do.

      Hope it helped-

        Yes actually. Matter of fact, I think i've found the identical one listed that the guy used (based on just the picture) : The Pilot PL-RY1 for $7.99

        I don't mean intermittent... again from memory, but the way it was explained to me was that the reverse lights do not get a steady source of power.. but a variable -- very fast, but variable... such that it wont sustain solid power to power the cam... but enough to trip a relay.

        ... then again I could have gotten some crappy data too . I know the cam works, hooked it up in the house just fine.

          Do you have LED taillights or standard incandescent bulbs? If it's LED then my guess is they are powered with a PWM signal to control brightness, which would match with what you are describing.

            Nope. They're not LED lights...

            I'm going to go test this again, using a straight-wired 12v power just to see..
