The  700R4 is a 4L60 or 4L60E, the 4 denotes the number of speeds the L is for longitudinal mount (front to back) the 60 represents the torque capacity (that's Chevy nomenclature) and in the case of the E, it denotes electronically controlled, versus throttle/vacuum controlled.

On all 700r4's the harness is only used to lockup the torque converter.  There are a few different wiring configurations and pinouts depending on the year.  If yours is definitely from an 84 you can use the wiring diagram for your year to determine which pin does what (see the tech pages on this site for the diagram).
