    I've been replacing all of the lenses and lights on a '93 F-150 that a bought a over six months ago, headlights, corners, turn signals, tails ... everything. It was in bad shape and I wanted to be able to drive it at night, safely above all, but also without getting pulled over and harassed.

    Up front, I even replaced the sockets for all of the bulbs. The turn signals are a 3157 dual filament bulb with a S547 socket. For some stupid reason, the aftermarket socket pigtails have no indication of which wires are which. There are three black wires, how stupid is that?

    So, I got out my meter and checked them, and then installed the turn signal socket on the right side. I assumed that the other socket would be exactly the same, so I wired it up the same way. Then I've got no left turn signal with the headlights on, and on the dash the left turn signal indicator lit up when I turned on the headlights. Okay, seems like a ground problem. I wired up a new ground connection for the left side, after which the fuse blows. At this point, I know something is very wrong. As it turns out, the order of the wiring coming out of the other socket was completely different, not reversed, but completely random. :mad:

    What a pita
    If all the sockets are toast makes me think flood recovery, probably just old.

    When ya get done with that could ya wire it up with a trailer light plug too?

    just kidding

    A few years ago, we were working on a model A truck.
    The repop light sockets that were available at the time, were mostly disappointing as a whole.

    The electrical contacts were okay, but the gaskets/seals to keep debris and moisture out were old and worn out. I also broke some of the sockets on the left side.

    The nuts were frozen on the turn lamp assembly and so the studs started backing of the plastic. I had the same thing happen on the right side. This time I got so mad I just ripped the whole thing off with the bezel. Then I cut slots in the studs with a Dremel for a screwdriver, and I hosed down the nuts with PB B'laster. It was a fun time.
    None of the aftermarket stuff is very good, but now that I've finished it, it's a huge improvement over how it was originally.

    Pretty nice truck! Heck, I'd spend a couple hours and just sand that bumper and rattle can it black...

    I've thought about that, at least until after Christmas. I don't need to be spending money on a bumper right now. Although, I don't know about black, maybe a rattle can metallic grey.
