It sounds like you have one of two problems. Either the wiring on the 1995 Ford Ranger is not converted as it should be to allow the brake and turn signals to work on the same circuit correctly, or there is a ground issue on the trailer that is showing up when the brakes and turn signals are applied at the same time.

If your trailer wiring does not have an inline converter, like the black box on the # 118325 T-One Harness, then you will need to purchase one and install it. The #118325 harness will plug inline with the tail light connector that is located along the inside of the left rear frame rail at the rear of the truck.

If you have the correct wiring on the Ranger, and the connector is working properly, testing without the trailer attached, you will need to direct your attention to the trailer. Check all of the grounds on the trailer for proper connection to clean, paint, primer and corrosion free parts of the trailer frame. If light brackets are bolted to the trailer frame these connections should be checked and cleaned also. Most trailer lights are grounded through their mounting hardware, so check these connections also if your lights do not have a separate ground wire.

I do not recommend towing this trailer until you have the lighting issues worked out, for safety.
