hey i was wondering i bought a ls obd0 harness cuz some one told me i needed it cuz i am going to do a ls vtec setup in a si crx and but non of the plugs up to the to the harness that comes from from within the car ok where the resistor box is there is two plugs and only one of the ls harness plugs up and on the pass side there is three plugs and only one plug onthe ls harness plugs up do i keep my original harness or do i need the ls harness and get some one to wire it up

 

Well thats the beauty of Hondas man. You can always use ur wire harness for just about every swap. Use your stock harness, you will just need to add 3 wires since your car is already an si.
Add 1 wire to vtec solenoid from ecu
add 1 wire to vtec oil pressure sensor from ecu
add 1 wire to knock sensor from ecu.
do a google search to find ecu charts for where to put these pins
Hope this helps

 

word thanks alot so i should sell the ls harness
