Front coolant bridge sensor an additional one(edit not put on aftermarket one 93 and older). The main one that feeds your computer the coolant temp is the one on the left of the picture that is green. I looked at a year older then your and newer and i couldn't find if it was from something else. No clue what it goes to ,but it might be for a fan ECU not sure more searching needed. There is a plug in there might be in the timing covers or the intake plenum.
