This is more like it I think...still suggest someone more knowledgeable checking this before imple menting.

I spent a couple hours on this over the holiday.

I used a DPDT - On / On switch. This switch has 6 poles with numbers 2 and 5 being common between the top and bottom halves.

In the configuration above, the hazards work as expected.
- Wire 30 (Constant power) energizes Wire 49 (Turn Signal Relay)
- Wire 49a (Turn Signal Contact) is ganged together with the L and R Lights

However, in the other switch position, the turn signal doesn't work properly - both L and R side lights come on when the stalk is flipped in either direction. This is due to having the L and R wires connected together at the switch.

The only two wires needed for the Turn Signals to work properly are 15 (Key Start Power) and 49 (Turn Signal Relay). But when you connect the L and R wires together on the same switch terminal in order to operate the hazard setting, then you will always get both right and left side lights blinking when you activate the turn signal stalk.

I tried multiple configurations on the switch but I was never able to get both features working at the same time.

I am going to attempt to get an 8 pole On / On switch to see if I can get this to work.

The switch is a standard Hella 001579-09 which is today available as a 001579-11.

It has a mating connector attached to a short wiring loom. That loom is Porsche specific part number 911 612 014 31 I believe.

Once the loom is separated from the switch you can read the contact designations (from the top clockwise):

30 - power in from always hot bus; a single red/black wire going through the connector on the front bulkehead to fusebox 1 fuse 2.

49a - two wires - one black/white/green going to the turn signal/headlight dim switch, and another black/white/green through the connector on the front bulkhead to position 49a on the turn signal relay.

49 - a single red/white going through the connector on the front bulkhead to position 49 on the turn signal relay.

58 - a single wire listed as brown (but mine is white) with diode P/N 911.612.249.00 connecting through a single pin connector to the headlight switch position 58a.

31 - a single brown wire with faston connector going to local ground.

L - power out to the left side lights; a single black/white wire going the bulkhead connector.

15 - power in from the hot in start and run bus; a single green/red wire going through the connector on the front bulkhead to fusebox 1 fuse 8.

R - power out to the right side lights; a single black/green wire going the bulkhead connector.

The switch has a key molded into it to insure proper orientation during connection; you can see that near position L.

The loom connector simply pushes onto the switch once the key is aligned.

To remove the switch from the car, disconnect the loom from the switch and from behind the dash, squeeze the two plastic ears, and pull the switch through the front of the dash.

By the way, this would be current flow without EFS engaged:

It looks like 58 lights the switch when the flasher is activated. A diode prevents reverse current...so the switch does not light up in other conditions...only when the switch is activated...most likely. I see my Haynes manual describes this "diode" as a "resistor"...that would most like just dim the light in the switch.

You say you have a new harness...is the switch an old one or a new one?

See post 15 above for the flow path of the turn signal power - green lines.

Here is my take for when the EFS is engaged:

When the car is not running, the flashers will work because power is available from terminal 30 (always hot bus). When the Emergency Flasher Switch (EFS) is pushed in, power is then taken from terminal 30, and all of the outputs L, R, and 49a are ganged together and powered by the flasher. When you activate the EFS the red current flow is in play. Power comes in from terminal 30, powers the flasher relay, which in turn powers the left side lights of the car, the right side lights of the car and the two turn signal lights in the dash.

The orange path to the left its the power to light the bulb in the EFS when the headlight switch is turned on so that you can find the switch at night.

When the EFS switch is not engaged, then power from terminal 15 (when the car is in start or run key position), power goes to through the flasher relay, but the outputs are not ganged. Power goes to terminals 49a and into the light switch to only power the car lights and gauge lights on one side of the car.
