Brake lights

My brake lights quit. I found a green wire out of the brake light switch hanging loose with little insulation on it. There is a 6 wire plug with a wire cut off on both sides does this green wire go there? On the opposite side where the wire is cut short. I can't locate a wire that would have been attached there. Does my turn signal switch have connection to the brake lights? The 8 wires out of the steering column have a two wire plug and wires go to the tail lights. Can't find a detailed schematic.Thanks for any help.

I'm assuming its the 66 that you mentioned in your Intro thread, disregard the red markings. The green wire (10A) runs from the brake light switch to the turn signal switch plug.

Thank you. I can't see where a wire was attached there before but so much has been tampered with prior to me I will try your advice. Also replacing the turn signal switch and wiring where it was spliced several times at the bottom of the column. Thank you again.

First, please put the basic info for your car in your signature so it will always be seen.

Figuring out how the brake and turn signal lights work on these classic Fords is hard. The bulb has 2 elements that do 3 things. 2 are controlled with the turn signal switch with flat springs and a contact hidden below the lever rocker plate. Often the problem is no contact at that point.

Also, the new TS switch will not have the plastic connection block. You must remove each wire by pushing in on small finger sticking out on the side of each pin. Find something to push it in before trying to yank it out.

Before you do anything, check that the bulbs are OK.
The 2 terminals at the base of the bulb often wear with vibration which eventually cause the light to stop working.
Don't connect any wires before you check this first.

As Driveway mentioned, please post the details of the car you have.
