OKAY... a little more Knowlegde know...

As I understand the wiring scheme, there a 4 wires from Hazzard-Switch to the Bulbs...
The switch get's a pulsed power from the relay, an only connects 2 of the wires (one front, one rear).

What I didn't understand:

The Light-Blue wire from the Relay got constant 12 V power, an starts to "interrupt" or "pulse" the 12 V, when the Flasher turned on...
How does this work ?

And do I need to connect the front- and rear-flasher seperatly ?

The flasher relay is a thermal device. There are electronic ones available but they work on the same principal, ie, they require a load before they will flash.

You should not need to connect front and rear flashers on a five wire rear as they are already connected.

Okay, Thanks a Lot to Martin !

So I found out how it works:

The Thermal Flasher Relay "stops power" shortly when "in use" and gives that "signal" to the switch (LB cable).
The switch is a mechanic only.
If you "turn left" it connects the "LB" to left front LG/W AND left rear LG/O.
If you "turn right" it connects the "LB" to right front W/LB AND right rear O/LB.

So I believe, I can't solve it with the Pekatronic Relay.
I wrote to the support, explanned that scheme, and asked them if they got an Idea.

Has anyone solved it here already with any other relay ??
