My Toyota pickup has separate directional and brake light bulbs with separate wires to each. The trailer's wiring plug has one wire for both. It's labeled "turn/stop". <br /><br />I spliced into my truck's rear light assembly for leads to go to the 4-prong plug that mates with the trailer plug but what should I do about the separate directional and brake wires? <br /><br />If I just connect them together to form one wire to go to the plug, I assume that would screw up the truck lights ie every time I step on the brake the directionals would come on and every time I put on a directional the brake lights would come on.<br /><br />Any input would be much appreciated. Thanks in advance.
