LS motor

I have an 90 SI do I have to change the wiring harness in my car to put in a 92 Ls motor

No, the wiring harness from your Si motor should hook up fine. You will need to change the ECU to one from a 90-93 teg 5spd but that should plug rite in too.

nope, a 90-91 motor plugs up fine...the 92 motor you have to extend the Purge Solenoid 2 wires, the map sensor 3 wires (both off these sensors have to be extended off the firewall), the coolant temp sensor wires, 2, have to be extended from the back of the block to the t-stat housing, the 4-wire O2 sensor has to be changes out for a 1-wire, and the distributor from a 90-91 model will have to be used.

a premade wiring harness for this engine running 90-91 ECU and Distributor and Exhuast Manifold, with 92 LS engine, and in your 4G hatch would require $180 for a harness, plus two core harnesses - your civic harness, the 92 Integra's harness. www.placeracing.com...get there phone number and call them...ask for gil. He'll give you more information on it.
