Please Help ASAP, 95 O2 Sensor Question

[roxanne@'95 gt]

searching thru my chilton '94 to '98 mustang repair manual, it states that on 5.0 and '94-'95 3.8 engines, there are 2 sensors: 1 is located in the left exhaust manifold and the other in the dual converter y-pipe. looking at the electrical schematics shows 3 pins on each sensor going to pwr gnd, ign run and ho2-s r+l respectively. the lower right pin on each goes to a "common" which is connected to other parts of the system, like the transmission speed sensor, mlp sensor, etc. jesters right. fomoco parts for things like this
