Brake light goof.

I got a 77 ford LTD that has been sitting for years... I've been freshening it up and had to do some elec...work to get the lights to work properly. I replaced the brake lamp switch but it still wouldn't work so I dug into the wiring and found that the hot wire wasn't hot anymore, so I got a lead off another source and reconnected everything. Now when I push on the brake, the lights turn on...BUT so do my front parking lights. Both of them. Any clue what I did wrong?

You got the wrong wire..............................

Find out why the original wire is not live any more and go from there.

I used the original wire going from the switch to the tail lights... But for some reason the front lights are also hooked up to it. I mean, it's all original. I didn't do anything to the rear harness. Just added power where power was needed. I guess, I'll try and track down that other wire that went to the switch. Although, if the wire I'm using is the original and it works... why would it matter where the power comes from?

Did you check the fuse for the brake lights?? Also I would clean all the socket ed bulbs and sockets really good. They get a white powdery corrosion in them and do weird things due to getting a poor ground. after cleaning give the sockets a shot of WD-40 to prevent future corrosion. Good Luck.

They are. But when a car sits for a while the bulb sockets get that white S*#T in them and it drives the system nuts. Bought a LTD Wagon that sat for a few years a while back for the 460 that was in it. We started it and drove it to see what kind of condition the engine/tranny was in. This thing had green slime and moss growing on it and I put a tarp over the seat to drive it. Anyway, The right front running lite worked with the brake lites, other lites worked with the turn signal lites, ect. We cleaned them all up really good, wd-40 ed them and they all worked fine. Bad grounds drive the circuits crazy. The shocks were soo.. bad!! I was going down a four lane divided and started pumping the brakes to a Polka song on the AM radio, it bounced so bad that we had to see how far it would bounce. The front bumper hit the pavement and almost wrecked us!! Did I mention the beer? Oh Well!

The circuit for the brake lights comes from (thru) the directional switch. This is why when you created a new hot source to the brake light switch your front directional lights also come on. Feedback thru the directional switch.

The problem is in the directional switch.

Remove the new hot wire you added to the brake light switch and find and correct the problem in the directional switch.
