Coolant temp sensor circuitry, injector lugs

[Steven Arnold]

What method do most efi computers use for measuring the resistance of
the coolant temp sensor - a wheatstone bridge, a constand current
source, or perhaps just a potential divider type setup?  (This question
may have been more appropriate for the efi332 list)

Also, the injector connectors used on late model Mazda engines, some
Mitsubishi's etc - what are they, where can the lugs that fit in them be
found?

thanks
