Cigarette Lighter Question???

[Joe K. 99 Zeee!!]

On the 3 prong cigarette lighter. Which connection is pos, neg, and ground?

I have to splice the 2 prong lighther wires to the 3 prong connection. I tried the left and right connectors but got nothing. There are two other possibilites left seeing as the bottom connector must be pos. or negative.

Thanks!

Got it...Trial and Error works well in some cases.

So, facing where the wires come out....

Left (+)
Bottom (-)
Right (not used)
