Fuel Pump Relay question

I can't think of any other grounds than the ones for the ECU, and all
the ones that meet up at the side of the battery tray, and the end of
the negative battery cable that terminates on the top of the trans
housing after leaving the side of the battery tray. That's why I was
asking if I'm missing any other ones specifically...
Speaking of sensor connectors....
I read somewhere (I think that sjmautoteck or whatever it's called)
that Audi (I believe) recommends some kind of dielectric type grease
that has a weird conductive property where electricity goes through it
in such a way that it won't short out two wires that are within the
same "glob" of stuff. I remember being amazed at reading the
technical description... basically the electricty only goes through it
at a straight line, so two wires close to each other can shoot
electricty through it, and never cross. I'd think this would only be
beneficial if the connector seperated from it's terminal.. and
supposedly the grease would bridge the gap and keep electricity
flowing... anyone know what I'm talking about?
Still have to go out and "experiment" with disconnecting the hall
sender connector, etc to see how the tach reacts. The tach has told
me twice now where the problem was based on it's behavior when the
engine dies. Straight to 0 was the ignition module failing (caused by
an out of spec coil burning it up... which I found through the burned
up module... lol) and Floating to 0 was a vacuum issue. Same went for
the cracks in the fuel pump relay solder joints... the tach floated to
0 as the gas burned off... So it does help eliminate what is failing
somewhat. I won't be able to experiment until Thursday though...
