Hi, New to this and have a question. Just purchased a 96 Tacoma 4x4 for my soon to be 16 year old son. Has a few problems that I am working through. Have one that is a real stumper for me. The brake lights work fine during normal daytime driving conditions. When the headlights are turned on the brake lights are on. I have check the wiring and have found nothing shorted together. I see a intergration relay in the wiring diagrams and was interest if anyone might know if this relay sticking would cause my problem. Thanks for any help.

See if the bulbs are in correctly. You may have single filament bulb in a socket meant for double filament bulbs, or the correct bulbs may have been forced in backwards.

You are right. I just finish working on the problem and that is what I found after repairing the wiring near the rear bumper. The previous owner had tried to wire in trailer brakes and had a mess. After cleaning that up I still had a direct short between the tail light wire and brake light wire. I found the bottom and center lamps in the passenger side swapped. Put them back in the right place and all is well.

Thanks for the response.
