Car USB socket installation, excess wires.

[Taffyboy97]

I’ve had a go at installing a USB dual socket in place of the factory fitted cigarette lighter in. VW Polo (2005). The old cigarette socket had three wires going into a connecter into the back. The new socket only has two terminals on the rear. How should i connect the new socket? Where should the third wire go, after connecting the live and the ground wires?

Suspect the third wire which will be tiny compared to the other two is for a light so you can see the lighter in the dark. You dont need that wire , needs to be made safe so it cannot touch any metal

As above, the third wire will be for a light.

if you look at the existing smoke lighter, you should see a bulb stuck on the side like a wart.

Why didn’t you get a dual usb that plugs into the 12v aux plug? (That’s a posh word for smoke lighter)

Thanks for the replies. I originally did as suggested, but my new, after market car stereo kept overheating causing the sound to cut out once it got too hot. Since disconnecting the usb port and taping up the wires, the stereo has been fine. Any ideas?
