set the dmm like you usually would when checking voltage....use the pos on the dmm..... put that on one wire and the other to a local ground.....which ever one reads is pos

that make sense?

Yepp, IF its 12V hot. not if its a 12V input of some sort.

Probe the power and ground. If it's +12v then just go by the DMM leads. If it's -12v, then reverse the leads.
