[Replacing cigarette lighter with USB socket (wiring)]

Hi,

Im new to the forum so sorry if this sound like a dumb question, but I want to be sure before connecting.

I currently have a TD5 and want to replace the cigarette lighter

()

with one of these:

However, the USB socket has only + and - terminals, whereas the old cigarette lighter has a black wire, purple/green wire, and red/yellow wire connected to it:

I'm guessing that the wires are as follows:

black - earth

purple/green - 12V

red/yellow - to connect the bulb

Could someone confirm this please? I cant test them as its a bit difficult to get my hands on a multi-tester at the moment. Thanks
