Flasher/blinker relay

[kevin v]

The turn indicators on my 1990 C2 cabriolet don't always cancel especially if I've used them for a minor turn of the steering wheel ( eg overtaking).
Engine and road noise ( especially with the hood down) drown out the clicking sound of the relay to remind me that my flasher is working.
I want to install an electronic sounder (piezo type) connected to the flasher unit so that it gets an input when the turn lamp is operating.
I'm hopeful that someone can help me witht a copy of the wiring diagram of the indicator circuit ( including the internal circuit of the flasher unit) so I can work out where to connect the sounder.
Thanks in anticipation

As the knowledgebank seemed a bit thin on this topic, I took some time to research other (non 964) sources to find out how the circuit might be configured.

I also did a little testing on my car and finally worked out what to do which turned out to be far less complex than I anticipated.

The result is that it worked well and now I get a nice gentle beep to remind me to turn off my turn indicator if they haven't cancelled automatically.

I'd be pleased to share the knowledge if anyone has the same problem and wants a 'fix'.

Send me an email to reldiv@gmail.com and I'll return the details.
