getting close!! help please.
getting close to putting my old truck on the road but I put my bed on today and hooked up the tail lights to find out that the brake lights stay on, possibly running lights. not sure which one but I don't want my battery dying on me, suggestions please

Check your brake light switch on the brake pedal your switch may be stuck pressed in or your pedal might not be fully extended out see if you can pull the pedal towards you any farther easiest things to check first

I believe the brake light switch on a 67 is mounted on top of the master cylinder on the firewall. Some will work both ways, but with the ign. switch on, one of the wires feeding the switch should be hot. Depressing the pedal should activate the switch and power go to the rear on the before mentioned harness. Are those two wire ends touching?
Shouldn't be hard to resolve.

Good catch jowilker them 67's have some oddball differences compared to the rest of the fleet. But one wire should be hot at all times even without ignition turned on I believe. That's how everything I've ever owned was. Buddy used to and probably still does use a bunge cord around pedal hooked to steering wheel to keep the lights from coming on when he parks it so it don't drain his battery

well, I looked on the firewall and there is no sort of switch for it, there is however a switch on the brake pedal itself. It has been wired into a toggle switch somehow and the toggle switch nor the brake switch itself make them go off. ill post photos of what I found.

1st you have to figure out which system to investigate. Push on the brake pedal and have a buddy watch the lamps and see if they get brighter or stay the same.

they stay the same, and I also unhooked the switch on the pedal lever and unhooked the turn signal switch and they still stay on. when the turn signals are hooked up and I turn them on then they kind of flicker but that's it.

check the taillamp wiring under the master cylinder to see if PO hacked into it. If looks OK then try unhooking the headlamp switch. If cross-curcuited on the inside of it it could send power to the rear lamps.

Some guys say theirs is the same, some say as you that it is hot always. My thinking that with the switch off the brake lights would not be burning and run the battery down should there be a malfunction.
This is not the only 66 that I have owned like that.
86Ford, That is not the factory master cylinder in your photo.

mine was moved from under the hood to the pedal. with the key in the off position I have one hot wire and one not. I'm not sure what to do about this but it is getting pretty annoying, I seem to have a temper when it comes to wiring issues and pretty immature about it as well. I broke my dome light cover, and broke the dash bezel pretty good when I got mad about the wiring and started slinging tools all over the cab.

I cant figure out much on this, I thought the switch might have been bad so I took off one of the switches in my door jamb for the dome light and hooked it up to make it the brake light switch and still the same deal, they will not go off. under the bed of the truck there are 2 plugs for the tail lights, one has 2 prongs and the other has 3. If I hook up either of those then the brake lights come on to stay.
