Hi all,

To improve the sound of my 986 2.5 boxster I recently bought an old muffler coming of an 2005 Boxster s
It is an Eismann mufler with Vacuum controlled Bypass valves .

I want to controll the Valves using a tip switch ( just bought an original one)
With the muffler I got the vacuum valve , a plastic container , the vacuum lines and a one way valve
also I got a "abgasklappen Relais 996.618.980.03" with 9 terminals
I think it was controlled automatically in the donor car by the ECU?

Anyway in order to use it in my set up i would like to ask if anyone has a Wiring diagram for this relay .
Hopefully it is a latching relay:_)

Any help is highly appreciated.

BR
