ecu terminal useage is the same as for the 87- 88/89's,, a couple wires are slightly diff in the 88/89 to the 87's but   it's not  of a great importance
one  thing i do recall is the  power  keep alive mem is   pull'd  from the main power  feed on the 87 , and on the 88/89 it has  a seperate power  wire from the  fuse links
also the 87-88  B38  connector is  in the same location,,but on the 89's  the B38 is to the left of the glove  box  and the wires are  of a diff sizeing , all useage is the same other  then mention'd

pin out for 88/89 is in the fuel section page 14-15 i beleave  or close to there

14: n/c
15: TPS
16: n/c
17: Intake temp (OVCP)

You can find the 88 pin-out on page 14-11 (Fuel section of the FSM).
