I'm tinkering again with the electronics in my car. First of all I managed to get the tacho to read the RPM correctly, thanks to a Dakota Digital universal tachometer adapter, recommended by Dave (owdlvr) in another topic here on GL:
Thanks for that!
And after that I took on a bigger challenge: I got a universal central locking remote controlled unit, and this is how far I got today:

All that's left now is the mechanical part... installing the actuators etc.
While working on the wiring I stumbled upon a problem: The fact that the bug has a single bulb in the dashboard for both left and right turn signals. And that's run by a wire coming from the relay. That was messing with the central locking, and I managed to change it. Now it's much better and the interesting thing is that the battery voltage is much more stable now and the gauges are not dancing in the flasher's rythm anymore.

And while I was at it, I remembered Joel saying on the auusie forums that there's an accesory position inside the ignition switch. I wanted to test that, and after installing a missing wire, it works now. That opened up some new posibilities for tinkering :P
