Steve: Sami's your man, he hasn't put his gauge in yet. Mine's installed
and there are bascally two leads about a 18 inches in length.From that
run two 18 gauge wires to the front gauge. As I understand it you are
saying these will effect the signal? Hmmm. Readings seem to show about
normal temps - 350C but what in your opinion would the readings be if they
 were the incorrect length - too high or too low? DC
