I have been having an intermittent problem with my left brake light on my 53 Club Coupe. All other lights work properly, but the left brake light only works some of the time. I have changed the bulb, brake light switch, checked connections and the ground; the head light, parking light, turn signal works on the left rear even when the brake light doesn't work. I was advised that the problem was the turn signal switch (original). I purchased a replacement switch from Dennis Carpenter but the wiring instructions are NOT understandable (new switch wires don't correspond with the original factory wires). Need help, Thanks!

I would recommend removing the original unit from under the steering wheel and looking for a loose wire or clean the contacts.

Already did that before ordering replacement switch, but didn't solve the problem. Test light shows no current at left brake light when applying the brakes.

Sorry, I can't help with the new switch, don't know wire colors. But your symptoms are classic for an open/dirty contact in the turn signal switch. I believe problem is not in the wiring. Left turn signal works, and left signal and left brake use the same wire from turn signal switch to the bulb. Left and right brake feed wire to the signal switch is the same wire, and right brake light works. Therefore, problem is in the turn signal switch itself. There are probably little copper contacts in the switch. In the neutral position, the brake feed is connected to two contacts, one for right and one for left. The left one is not making contact when in the neutral position.

I have already installed the replacement switch and thru much trial and error the headlights, parking lights, right side front and rear turn signals, left side front and rear turn signals, right side brake light are all working properly. The left side brake light does not work, but when applying the brakes the left turn signal indicator light on the dash flashes/blinks. Thus the need for wiring diagram to determine where left brake wire goes on the junction block under the dash. The wiring instructions included with the replacement switch is useless, the wire colors don't make sense. Thank you!

Hello Mike. A company called JEGS sells a color-coded wiring diagram for 1952 and 1953 Ford cars as their part number 555-19681. It appears to be showing a pink wire and a black wire running to some sort of junction block. Hope this helps!
