RF Hazzard Circuit

[Straversi]

Slowly but surly I'm getting a handle on the wiring. I have the RF harness and individual indicator lights.

So I take it, this is the (DPST) Double pole/Single throw toggle in the kit? It has six small spade connectors, labeled 123 running lengthwise and 456 running lengthwise down the other side

68369

Am I reading this schematic correctly?
Where the DK GRN left front turn, YEL-left rear turn and Left turn indicator wires together (some kind of a bus I assume) add a wire that attaches those three lines to one of the DPST connections (Connection 1)
Do the same for the Right side signals and indicator (Connection 4).
Splice or bus together a second small spade connector on the pink Hazard Flasher line and connect them to the two other corners of the DPST toggle? (Connections 3 and 6). The middle connections 2 and 5 would be blank.

68368
Does that make sense?
Sorry, I feel like the kid raising his hand in the remedial wiring class and slowing the class down but I'd rather ask questions than burn this thing to the ground.

Yep; you've got the right switch. And you found more information on how to wire the hazard flasher than I did in the RF manual.

The end-all, be-all post on switch wiring direct from Jeff Kleiner (Post #18 of http://www.ffcars.com/forums/17-factory-five-roadsters/546649-dash-layout.html):

“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

Told you it was screwy but trust me, it will work.”

I followed Jeff's instructions to the letter and everything worked perfectly first time out of the box.

Thanks, do the DPST and DPDT switches keep the left and right sides isolated? Is that the reason for the multiple inputs?

Yep. Also, on my car the hazard switch was ON/none/ON; there was no switch position at the center. Exactly what I wanted, so that when the car is off all the switches on the dash are in the down position, and when something is on the switch is in the up position.
