So i picked up a 91 Civic Si. The car was in a previous theft and some stuff is missing. The owner had swapped the engine for a JDM SOHC ZC, the issue, when the car was stolen thieves took the engine harness and distributor. So I lurked around and found out that a another Si engine harness should do the trick, is that correct? Also could I use a harness off any other trim level civic? Also what distributor can I use off a different engine?

 

As for the engine harness, it would be the easiest to use another Si harness. The rest will not completely just plug right into the car. The HF can if you switch some wires around, but just get an Si harness, it will save you alot of headaches.

If the car is obd0 still, you can use a d16a6 distributor for a SOHC ZC.
