:).  Well, there is only one way I can think of to get the resistance
value,
find somebody that has a TT moudle, unplug it, and test the resistance 
when it is activated, this would be the easy way of course, and I am
sure
there is another way.

Hmmm, I think I would have to answer when the coolent temp changes for
number 2, what do ya think?

Heres an idea,  we know what the signale to the DPR needs to be 20.5mA,
which is 13:1. So you could put a meter on the DPR and hook a fairly
big pot in place of the temp sensor, you could then get a ballpark
value and tweek it with fixed resistors,  This is another hack way
to do it.  

I may just have to take a ride to the local electroincs supply (I can
get one of those nifty cases a radio shack) and try this out.
