    To correct my last post. The wiring in the back is different than I thought.



    the wires running to the back are different for these Vans, Since the brake and signals are separate then an adaptor is required to make the lights work properly, reese make this adaptor. if you alot of towing I would suggest the most expensive unit that uses a power feed that goes to the battery and then hooks up to the lights at the back



    VAN white = brake

    brown = tail lights

    lt blue = left turn

    dk blue = right turn

    hook these wires to the adaptor and you will be on your way.

SOURCE: tail light wiring connectors and wiring diagram

A test light checking each connector would be faster and easier to do. Maybe somebody may have a illustration for you but by far a simple test light is all you need with a helper turning on the different lights as you check them out and writing all your findings down

1998 Ford Explorer has factory trailer wiring ... won't light the left turn signal light on trailer or left brake light ... bulbs are good, all lights work when vehicle lights are on except the left...


Use this as a guide and a 12 volt test light, or multimeter to see if power at proper terminal from truck. If power there, then connection at trailer plug, or wiring from there to tail lights on trailer is faulty.motor1258_22.jpg

Hi got brake light but no tail light fuse all good can any one help me please


Check the rear harness wiring harness for corrosion or a broken wire. Should be the brown wire that power up tail lights. Also if you have trailer wiring disconnect it and see if it goes away. Trailer wiring very often cause high resistence due to how they are connected.

Need to know where fuse for trailer lights hookup is located on a 2000 ford expedition eddie b edition


The trailer light's are just connected to the wire's going to the tail light's so the tail light stop light and indacator's are using the same fuse as your car. If all the light's on the trailer are not working and the tail light's on the car are then most likely it's a bad ground connection. Only one ground wire is connected to the plug so all the light's depend on it.

What number is the fuse on the trailer brakes


i believe the trailer brakes run off the same fuse as the tail lights no extra fuse all the ones ive seen the trailer lights just fuse into the wiring harness of the rear tail lights so if your brake and turn signals works your prob is gonna be in the trailer lights them self or your connection in the wiring right behind the rear bumper. Hope this helps

I have tail lights on pu but none on trailer when hooked up i replaced the plug wired same as old one no trailer tail lights I have turn & stop lights I have checked the fuse and still no juice to plug...


if you have nothing to the receptacle on the truck but the tail and stop lights still work, look under the rear of the truck near the receptacle , there should be a connection in to the main wiring harness...maybe its unpluged,dirty or corroded
