If your cutting off the car charger adapter and splicing the wires look at the wires. One wire coming out of the charger is rounded and one has flat edges. The rounded wire is your positive lead and the edges is your negative. To insure your correct go to the charger where the wires comes out just in case you had already split the wires. Last resort is to take the charger apart and look how the wires are terminated. Remember if you cross polarity when wiring up you will smoke it. Hope this helps
