I am trying to make the 12V power in my armrest be switched. I have a 12V relay, expecting that I would be able to find a switched 12V wire.The relay is otherwise wired correctly, because the 12V port works through the relay if the relay is being energized by the constant 12V power line the port is usually wired to.

However, when I try to wire it to the ACC wire it's not working. It looks like that wire is only getting ~6V. I found what I think is the ignition wire, but that is only ~2V. I'm really not sure if I am getting at the right wires, none of the information I can find on the internet regarding wiring colors lines up perfectly with what I'm seeing.

Anything blatantly obvious I am doing wrong? Is there another wire in there that is actually switched 12V? I'm having trouble getting useful information from what wiring diagrams I can find.

Thanks for any help guys.

 

Seems like a lot of extra work using the relay. Why not use a fuse tap on a switched circuit in the fuse panel and run a new wire from the fuse panel to the console?

 

I am trying to have the 12V plug in my armrest be switched, not the one on the dash. So I don't know how difficult it would be to run a wire from the fuse panel to there, vs. just finding the right wire to use to activate the relay.

If you can give me a little more detail in how to run that wire I will definitely look into it, but if you have a way for me to figure out which wire is switched 12V in that bundle under the console I can make the relay work.

Thanks!
