[Diy_efi] two part ect sensor Q

1) On a mid-90's GMC full size pickup, what electrical range does the
coolant temp guage read in? Truck used to have a TBI 4.3L, I now have
an LR4 (4.8L Gen-III) in the my 93 GMC Sierra, and I'd like to get the
temp guage working.  The service manual has not been all that
informative on detailing how the temp gauge works. I no longer have the
original engine, so it's hard for me to figure this out. Anybody know?
I believe it's a 5V dc circuit, but am not sure. 

2) I plan to retain the stock on in the stock location (drivers side
cylinder head), but run a seperate one on the passenger head. The port
in the head for the ECT sensor is a 12 x 1.5mm thread, so either I need
this thread, or a 1/8" NPT fitting, as there are adapter bushings
available that have a 1/8" NPT Female with a 12 x 1.5 mm male. 

Any help  is appreciated.
