use the DX harness

 

your harness should work.

 

Modifying the DX harness so it will run the LS is much simpler than swaping out the DX harness for the LS harness into your car.

 

if you've already converted your car for mpfi then its just a matter of swapping

Most of the wiring is done. You have to change some wires around because you are going from sohc to dohc. I'm not sure which sensor you need to change the wiring for. I think it might be the tdc sensor or the crank position sensor, not sure.

 

you already do that when you convert to mpfi
i have a std hatch and when i did the swap i just converted to mpfi and called it a day

 

As long as its a 90-91 b18a its plug and play as far as wiring..If its a 92-93 then you have to either convert the motor to pre-obd or convert the car to obd1..

 

doesnt matter what year motor it is long as you use the obd0 injectors and distributor

 

and what about the knock sensor?

b18a/b doesn't have a knock sensor.
