It will essentially come down to relocating a bunch of the wiring and running a '90 or '91 2.5L turbo SBEC.
The fuel rail sub harness, ignition coil, TPS/AIS, will all have to be relocated. The ignition coil will have one wire eliminated due to the ignition coil differences. The cam sensor and crank sensor wiring should be able to be repurposed for the distributor (and relocated). You would have to check pinouts in the '91 FSM to be sure though. If it were me, I would convert the '91 R/T harness rather than use a turbo Caravan harness. That way you wouldn't have to deal with body differences like headlights, relays, and wiring lengths. A '90 or '91 turbo 8v Spirit harness would be ideal though.
Wiring wise I actually used the R/T harness that was in the car with one exception- The front alt harness was from a TBI car of the same year!Originally Posted by MILKCARTON
I simply extended the cam sensor plug over the alternator to the distributor and the used the R/T fuel rail harness on the SOHC fuel rail. Very little needs to be changed. I think for the TPS and AIS I just extended the wiring.
