For all those running Autronic ECU's - has anyone bothered dash mounting a female 3mm (audio) jack plug running direct to the serial interface on the ECU. I've been thinking of doing this for a while so I can easily patch into the dash with the standard PC serial data link cable. Instead of having to pull the kickplate off the passenger floor every time I need access.

Anyone tried this? Or see any issues with it?
Cheers.
