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.

You need an adapter, Skiffer.<br /><br />Any auto parts store, even Wal-Mart, has them.<br /><br />Good luck. :)

skiffer,<br /><br /> JB is right, you need the adapter. I used to have a Toyota pickup and tried to hook the trailer lights in without one. All of the lights on the truck and trailer would flash when I turned on the turn signal :rolleyes: . Buy the adapter.<br /><br />RCS

I agree.The adapter is really nothing but a relay.You hit the light(which ever one)and it energizes the relay sending power to to the boat lights in the correct fashion.
