    Hazard light switch wiring

    How do I wire this hazard light switch? This is the switch that came with the complete kit. I'm using the Ron Francis wiring and there are four wires but the switch has 6 terminals. (The internet search got me all confused. Some guys are using diodes, SPDT, etc.)

    Connect the green and blue wires to two pins on the same end of the switch (either will work), and then connect the two red wires to the two center pins.

    Sounds like you have the hazards working but, here is some helpful I got from Jeff Kleiner. It discusses the various dash switches, including Hazard Wiring. The full link is provided below. Jeff's comments on the switches is post #18.

    Jeff's Words
    ON/OFF/ON is turn signal--- Land the gray "turn flasher feed" wire to the center terminal Join the yellow ""left rear turn" and the green "left front turn" wires together along with 3 extra pigtails (we'll get to what to do with them in a minute). Join the light blue "right front turn" and the white "right rear turn" wires together and include 3 pigtails with them as well. One pigtail from the yellow and green set goes to one of the outer terminals of the switch, another will go to the left turn dash indicator and the third one will go to the hazard flasher switch (again, we'll get there in a minute). Do the same with the blue and white wire set---one of the pigtails goes to the other terminal of the switch, one goes to the right turn dash indicator and the third will go to the hazard switch. After this you're done with the turn signal switch. To make the dash indicators work you'll connect the respective pigtail to one terminal of the lamp and connect the other terminal to ground.

    ON/OFF switches are used for accessories like the heater blower or cooling fan---power goes to the center terminal and the feed for the accessory goes to the other.

    ON/ON switch is for High/Low beam toggle. Since you're using a foot switch it doesn't apply.

    ON/OFF/ON gets a little screwy... This is a DPDT (double pole double throw) switch that gets used for the flashers. It really should be a DPST (double pole single throw) ON/OFF switch. They have been providing this same switch for years and the only reason I can come up with is because a DPST is not available in this style but it will work. Take the pink "hazard flasher" feed wire and connect it to BOTH center terminals of the switch. Connect the pigtail from your yellow/green pair to one of the outside terminals. Connect the pigtail from your blue/white pair to the other terminal on the SAME end of the switch. This leaves the two terminals on the other end of the switch unused. The switch will have 2 OFF positions (because there is nothing connected to the other set of terminals) and 1 ON position. If you wanted it to have 2 ON positions you could run a jumper from the terminal with the green/yellow to the open terminal on the same side of the other end and do likewise with the blue/white. In that case the center switch position would be off and flipping the switch either direction would turn on the hazard flashers.
    Looking at the back of the switch it will be like this:

    OPEN--------OPEN
    PINK---------PINK
    Y & G--------B & W

    OR

    Y & G--------B & W
    PINK---------PINK
    Y & G--------B & W
