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

ok, well i dont have the vehicle vin #, just the motor and computer and everything. right now we have some sensors from a late 80's 5.0 in it right now and they seem to work, but im getting another set to try tomorrow.

phomed ford and since i didnt have the vin, the guy was a total prick and wouldnt help at all, so that idea is out.

the motor is in my bronco 2 and was purchased as just the motor, without the vehicle.
