Question about 2002 Subaru Impreza

1 Answer

Brake and taillights not working...I had a towing package on my 2002 Impreza, the trunk was leaking and the control unit for the trailer got flooded and shorted. Now my brake and taillights are not working, the fuses are good and so are the bulbs. The reverse light and turn signals work. I have completely removed the fried control unit.

    My guess is I fried the relays also, but before I start replacing parts I want a second opionion

    It wasn't a relay- I fixed the brake lights by replacing one of the large 50amp fuses it was ???2. I am going to replace the switch on top of the steering column next because none of my parking lights are working

I think this is a mechanical problem ... when you brake it refuse to send a signal to the tail lights.
I suggest that you need to check the terminal block connection between them.

    Yes you're right' , cause the that relay are the one switching your tail lights..you've said said that fuses and other lights are working properly which the tail light connection also connected at the same circuit' so it means the problems in on the switching.

Where to find the wire going to the trailer towing plug for the braking.


As far as I know, your trailer towing package does not include a circuit for trailer braking. These packages normally only supply taillights, brake-lights, and turn signals.
RV sales and service dealerships should be able to help you.
God bless your efforts.

When i hook my trailer to my 2002 ford superduty i have no running lights on trailer.brake and signal lights work fine.WHY?


Hello, if you only have taillights on the trailer and no side markers, check your bulbs first. The bright side is used for the Brakes and turn signals and the normal filament is used for the running lights.

If you use a test light you can find the pin on the connector which runs the Running lights. Sometimes the wiring harness will pick up the running lights off of the taillight in the bed of the truck. You would look for a wire going up into the taillight housing from the Trailer plug.

If you are the original owner of the truck there was a small package of Relays and wire ends that came in a plastic bag. It could be stored with the jack. This package had wire color information and instructions for Electric brakes. It also color-coded the Trailer plug-in socket as they use the extra pin holes for the Electric brakes. All the wires are discussed.

If an aftermarket unit was wired in the running light, the wires could be any color. The industry tried to put in a standard, but instructions still say if you don't have one color, its another. That is still vague.

My 1996 Toyota 4Runner is equipped with a factory tow package; however, I'm unable to locate the plug for trailer taillights.


If you don't have a 'plug' for the trailer taillights, then the trailer renter, like Uhaul, sells bulb adapters that hook into the tail brake and light lamps that can power the trailer taillights.

I remember, I had a 1980 Suburban that didn't have a 'compatible' plug, and that's the way we resolved the problem.

Good luck on this towing.

How do i install a wiring harness for a trailer on a 2002 ford focus wagon?


  • Loosen and pull back the carpeting in the back of the trunk behind the taillights.
  • Step 2 Remove the plastic wingnuts that secure the taillight to the vehicle's body.
  • Step 3 Separate the taillights from the vehicle's body, but do not disconnect the wiring.
    Installing the Connector
  • Step 1 Examine the wiring harness on each taillight. There will be a plastic connector on each side that must be separated to insert the wiring harness connector.
  • Step 2 Thread the trailer wiring connectors through holes in the body behind each taillight. Follow the instructions provided with the connector to determine which connector belongs in which side of the vehicle.
  • Step 3 Insert the wiring connectors into the vehicle's wiring harness.
    Reinstalling the Taillights
  • Step 1 Push the taillights into position against the body and reinstall the plastic wingnuts that secure them. Be careful not to crush the wiring.
  • Step 2 Route the trailer wiring underneath the carpeting in the trunk, so that the trailer connector can extend out between the trunk lid and bumper when in use, and be tucked into the trunk when not in use.
  • Step 3 Reposition the trunk carpet over the taillight housing.

    I do not have power on the aux. terminal in the trailer plug on a 2008 dodge ram. Any ideas?


    You have got 7 pin trailer connector that was included in the optional trailer tow package. This trailer tow package also includes an electric trailer brake wiring provision that terminates at a connector located on top of the large body harness connection under the instrument panel to the left of the break pedal, as well as an electric trailer brake pigtail harness and an instruction card that are stored in the glove box when the vehicle is shipped from the factory. You will need to add an electric brake controller of your choice that will plug-in to the harness and that will also give you power on your auxiliary circuit.

    Rear taillights and turn signal lights not working


    I asked that becauses of the wiring for the tow setup. If the previous owner had uhaul or one of the other tow companies out there install the wires for the tow package they use a crappy little product that they clamp to the wire and push a pin that cuts the casing and connects the circuit. It also seriously weakens the cables, and lets water in to the wire. Since you have a tow package I'd focus on those wires back there sounds like you may have a short. Those pins do have some wire exposure when installed right and I've seen them bundled and taped on the early 2000's explorers without being individually taped first, which leads to shorts and non working turn signals and brake lights.
