PTC wiring for Passenger Car Lighting questions..

TheDude23112OGR Forum Member

There are two wires going to the rollers. Is one positive and the other negative?
If there is a pos and neg does the PTC get connected to pos on one roller and pos on the other roller?
If there isn't a pos and neg on the rollers, can you connect either wire on PTC to either wire on rollers?

Most passenger cars have two center rail wires, one from each roller. The ptc is connected from both those wires (one side), the other side is the + going to the led's.
