Hi folks,

I have a 41R140 AC/DC Combo Adapter. Unfortunately, it didn't come with the cigarette lighter cable. It has a small three-pin connector. Does anyone know what the pinout is of this connector so I could fab something up?

Here's the cable I'd need, but I'm way too cheap to buy one:

Thanks!
