    IMG_3881.JPG IMG_3880.JPG aloha fellow forum dwellers... so I've been tinkering on the new truck, doing the usual new acquisition maintenance, and I ran across this odd looking connector down by the battery tray, never seen one like it on any of my previous obs trucks. Any ideas?
    Thanks gents

    Edit: after extensive web searching(how would you describe that plug/connector in a google search) looks like a block heater cord would plug into it.

    Too light duty for a block heater plus the cord wouldn’t go into a harness - it would have a 3 wire cord going to a wall plug.

    Looks like a horn connector to me.

    Correct.not block heater...wires run into the headlight harness, after that I lose them.didnt want to start pulling the loom/harness apart.but curiosity is getting to me, so I may have to. was hoping someone on here would chime in and drop some knowledge.
    The truck does have the VYU plow package. Could it be for aux/plow related lighting?

    Horn. Just put a test light across the terminals and press the horn, you will "see the light"! That plastic end snaps onto a factory (usually Fiamm brand) horn.

    Thanks n earlier post suggested horn.tested it and got nothing.turns out there was a break in the wire where it came off the headlight harness. Butt connector and now I have juice to the plug when the horn is depressed...
    is this for a dual horn setup? there is already a horn wired in on the vertical support in front of the condenser
