    I see no added splices between factory hookups. I've checked all grounds as much as possible. no signs of breaks or corrosion that I can see. that's why I figure that I'll just run a jumper from taillight to trailer connection. just need to know which wires to splice into on both ends.

Hi

1. Check to see if there was any trailer wiring spliced in, underneath, by the back bumper, if there is or was splicing done you may have wires corroded through. Look for green color on the wires.

2. Check the bulb sockets. You have to open the tail gate to get to the 2 screws on the tail light lenses.

3. Make sure you have good ground at the tail lights.


Please get back to us if you have further query else please accept the suggestion.

Extend a simple BATTERY JUMPER CABLE...

In MY PAST ... (borrowed: co-owned) rather than

Rather than tamper with the trailer... or my truck
I used the Factory connecter Conversion JUMPER

Easy... Running lights & license... plus
Left & right turn signals...

Easy to trace trailer wires...

Check the plug wiring again on the truck. You have a wire crossed , when you hit the lights and it only blows with the trailer, then there is a crossed wire on the truck. What seems to be happening is your sending power to the ground for the trailer. You can check the trailers ground with an ohm meter, then make sure your truck ground matches that pin. You may know this , but green rght turn, yellow is left turn, brown is parking lights, black is brake lights, and white is ground.

Have a four flat utility trailer wiring. Need to know which wire to splice into for left turn signal, brake & running lights in the back of van. Also need to know for right as well.


the yellow wire is the left signal the brown is the taillight wire the green wire is the right signal wire and the white wire is the ground wire.the brake lights work through the signal wires.think of it this way yellow markings on the roadway is left of the car,green grass is right of the car brown is the darkness of the road behind you and the only thing i have for white wire is clouds(even if its opposite of ground)

either bypass a new wire or trace back for break /connection, if it is anything like a dodge truck wiring it was much easier to run new wire to left turn, I don't know what the hell these engineers think, But im sure there is a reason and it is definately not for the cunsumer.

Trailer lights have two wire out of each fixture left turn goes on left side Right hand turn goes on the other side Tail lights connect how and brakes connect how?


One wire is for the brake/directional filament and the other wire is for the tail light. The fixture should be grounded when it is attached to the bracket. To test which is which (the brown wire is USUALLY the ail light) make sure the fixture is grounded and touch a hot wire to each of the wires coming from the fixture. Watch to see which wire lights up the brighter filament and this is the brake/directional light. The dimmer filament if the tail light. Brakes lights and directional lights are both the same filament. Wen the brakes are applied, both lights are activated. When a direction light is turned on, it simply flashes the brake light filament.

Check the wires on the trailer. if those are good then you might need a better ground.

2001 Sportage Trailer wire connections


brown to the tail lights. yellow to left turn signal. green to right turn signal. this is a basic 3 wire hook-up i use all the time w/4wire connectors for all trailers. white wire is not used. ground is established when you hook to the ball.
to find the correct wire to splice to, use a testor (has a clip to the bare wire, and a sharp point to the truck frame). using a needle, push it through a wire to rear light harness. turn on the turn signal. check if the connection is the blinker, testing until you have the blinker wire. the tail lights can be attached to the license plate wire. brakes and blinkers use same wire, so brake lights will work whenever the turn signal is attached.
to be sure everything is working right, have a second person go inside the truck and work the signals, brakes and lights one at a time while you are at the back of the trailer telling what to do.
