thank you for your help with my 68 f850 brake light issue. I have another question. I replaced the stop light switch and tested to make sure its good, and it is. Since i know now that the brake lights are controlled in the turn signal switch, I located the wire for my brake lights. I tested the wire with my test light but the light does not come on when i depress the brake pedal, does this mean that the turn signal switch is faulty??? Thank you again!!
