    Its an auxiliary electrical pigtail to send power to the dump valve on the rear trailer axle.

    I have seen a third air line on a few stretch trailers.
    Similar to a air assisted sliding tandem to open and close pins.

    Most of the stretches I've been around used the red gladhand hooked up to a different gladhand to release the slide pins.

    I've plumbed in a manual valve on those so I don't have to switch the line.

    I've seen stretches with valves too, I shouldn't of spoke in absolutes. But the flats I pulled you switched the gladhand.

    What do they use it for? I never see thier axle up and why not a button like the stepdecks to slide the axle. what situation do they use it in. to drop the trailer low enough to get the height to 13 6?
