L-Jettronic tuning/Milano questions

["Bain, Bill" <Bill.Bain@domain.elided>]

Sometime ago, there was a Website that I believe was done by a European
gentleman who had done some pretty extensive investigation of the Bosch
L-Jet ECU and tweakable values.  No idea whether the Website is still
up, but here's the URL:

Milano questions: 

1.      My OEM radio antenna (non-motorized) has become loose in its
mounting on the rear fender  Tightening the large nut on top does not
good.  How to those thing mount -- it appears that there's some sort of
lip on the both of the antenna that pulls up against the sheet metal
when the top nut is tightened but I'll be doggoned if I can figure it
out.  Help!

2.      Where is the water temp sensor that drives the temperature gauge
located?  My temp gauge has gotten very flakey and I'd like to
check/replace the sensor if cleaning the contacts doesn't work, but I've
got to find it first!

3.      Ditto for the sensor that drives the oil pressure light and the
separate one for the oil pressure gauge.  The gauge quits when the
engine warms up and the light never goes out.  Hans told me that the
sensor for the light was disconnected since he replaced the sensor with
a threaded plug since he says that the oil pressure light sensor very
often leaks.  Still I'd love to jump the socket with a resistor to stop
the light, and having a working oil pressure gauge seems to me to be a
good thing.
