[urq] New quattro

[Andrew S Basinski]

Hey guys, thanks for all the great info.  I'll have to look into 
swapping the coolant for the boost gauge, that may kill two birds with 
one stone.  I did notice a strange (empty) vacuum filter in the glove 
box, so that may have occured before.

On installing this coolant gauge-let's say I get the gauge, and get it 
properly wired up.  The temperature sensor is my biggest concern.  I 
found one at the front of the engine under the radiator hose, and I've 
found sensors available on ebay for less than $20.  If I bought one, 
swapped them, installed the gauge, what will I need to wire?  Right 
now, there is only one wire coming out of the sensor.  Though I haven't 
traced it, I figure it goes to the ECU or something.  Will I have to 
run a second wire?  Can I just swap the sensor and reconnect the one 
wire?  The ones on ebay show a plastic connector with what appears to 
be 2 prongs.  The one on my car is just a single outlet with no plastic.

As for rustproofing- what are my options?  Undercoating, regular wash 
and wax?  I'm not in buffalo, but rather in boston (and sometimes 
syracuse) but the car will see significant snow.

#3, my windshield washers don't work.  The wipers go, there's fluid in 
it, the tubes are clear and ready, but nothing is going.  It's got to 
be the pump, but before I replace it, could it be the wiring?  Should I 
just scrap it and get a new one?  There's some on ebay for 15$ or so.

Lastly, thanks so much for the help already.  You guys are fantastic, 
I've already got answers to a bunch of my questions.  Just some 
comments on my car- I have electric diff locks, should I expect there 
to be a vacuum behind it anyways?  My seats are original, but I have no 
intention of refurbishing them.  They look fine, but the driver's side 
bolster and back switch don't work.  If I replace them, racing seats 
will probably go in.  David- is that your car with the black wheels?  
It looks good, but I'm still on the line.  I'll try and get some photos 
so you can see what I mean when I say silver(ish).

Thanks, and expect more questions in the future.
