Pollak manufactures electro-mechanical goods for the tow hitch industry, and has been in business since 1909. Their product line includes connectors, switches, sensors, jacketed multi-conductor wire, junction boxes, hitches and trailer plugs. Their trailer plugs are made from plastic to eliminate corrosion and molded with dual grips, have an auxiliary pin designed to carry up to eight-gauge wire, and are embossed at every terminal with the color of the wire to be attached at that terminal. Wiring a Pollak trailer plug is a straightforward project.
Locate the screw holding the outer case to the inner terminal hub; it is at the end of the ridge where the name "Pollak' is embossed. Use a screwdriver to remove the screw, then draw the case away from the terminal hub.
Insert the seven-conductor cable through the small end of the plug case, and slide the case down the wire until it is away from the work area.
Use a box cutter to separate one and a half inches of the cable sleeve from the seven wires inside. Be extremely careful not to damage the color-coded insulation on any of the separate wires.
Strip one half inch of color-coded insulation from each wire, then insert the bared copper strands into the appropriate terminal in the terminal hub. All Pollak trailer plug terminal hubs are embossed with the name of a color in the plastic adjacent to each terminal except the terminal in the center; it takes the purple wire. Tighten the securing screw in the top of each terminal down onto the wire until it does not move at all.
Slide the outer case back up the cable and over the terminal hub until it is fully seated, then reinstate the fastener.
