cat 3116 questions

ok, not sure this is the right forum to post this but here goes. we have a newly purchased 1991 kodiak truck and there appears to be a few wires unplugged that I was wondering if anyone might know where they go too. But what were really looking for is the temp sensor. The temp gauge in the truck doesn't move from the low end at all. Ive snapped a few pics and appreciate any help.
