Use your harness. Convert to MPFI. Use an OBD0-1 ECU and distributor adapter. You'll need OBD1 injectors and an OBD1 LS distributor. You'll also need to wire up a 4 wire O2 sensor as well.

 

how do i convert it though n what ecu would fit mine thats mainly what i needs help on mostly wireing n converting
