    Looking for a 12V constant power source somewhere under the dash. Already know (and use) the one in the microphone grille. Need to tap ~2.5A max. Thanks in advance for your help.

    You can also do a simple mod to have constant 12V power at the convenience plug. Just search... :cool:

    Thanks. Unfortunately I don't really want something always connected to the OBD port (I like my installs to be all wired-in without any unnecessary wires showing). As for searching FlatSix911, I did, nothing popped up (here or on google, go ahead, search "12V power at the convenience plug", or even "12V convenience plug" :) - all I found searching was OBD port and microphone grille). I know there is supposed to be a 12V source in the cabin somewhere, but I don't have access to the service manuals. Given that I'm running wires through the firewall already, I think I'll just tap one of the fuses using one of these.

    Are you willing to remove the driver's side kick panel and tap into the wiring there? If so there is a source. PM me.

    I believe there's also 12v at the rear-view mirror console in some iterations. I used that for my dashcam.

    Thanks all! Useful info a bout which relay this is (something I would be able to look up easily if service manuals were available).

    Thanks a bunch. This is the perfect solution for me. With the added bonus of easy reboots on my dashcam and safety in removing/inserting the memory cards.

    PS I also thanked Ingineer.

    Good point about the lack of service manuals. The relay is easily removed and replaced as pictured above.

    Glad to help share the information. Ingineer came up with the mod.

    Does anyone have a chart for the relays, I thought it would be on the fuse page. I assume the silver tank is the air tank for the air suspension?

    I'm still trying to find a fuse diagram for the newer long/skinny/single fuse box in recent as well as the refreshed Model S -- anyone have a diagram?

    The fuse and relay list is usually printed on the underside of the weather cover ... did you check this already?
