What Gauge Wire does 4-Way Trailer Wiring Use  


What Gauge Wire Is Required On a 4 pole flat connector for trailer lights


Expert Reply:

Typically 4-way wiring consists of 18 and 16 gauge wires.

For a 4-way that has all 16 gauge wire you would want the Wesbar 4-Pole Flat Connector # W787264.

The part # HM38138 uses 18 gauge for all wires but the white that uses 16 gauge.
