Negative	L-	no recommendation (black)
2-wire grounded DC Power System
Positive (of a negative grounded) circuit	L+	red

Which wire is ribbed white or black?

The Neutral Wire Is the One With the Markings The insulation is generally fused together, and one of the wires bears white a stripe or ribbing, while the other one doesn't. You might have to pull the wires apart to see this. The wire with the ribbing or stripe is the neutral wire, and the other one is hot.
