I have the radio and Nav out replacing with an Android and decided to replace a cigarette lighter also. Lighter has a Positive and a negative. Wires coming off the old lighter are Pink (with a green stripe) and white? In a car red is positive. In a house White is Hot/Positive? In a cigarette lighter? Hope please.

 

The center contact will be +12v
The outside (cylinder walls) will be ground.
