i've been looking on websites that u can send your harness an what ever engines harness an they convert it but there is none for a si harness to the obd0 b16a soo can i just use the harness that came with the engine?? or does anyone know of a site i can go too if not

 

u can use the harness that u had in ur car before to get converted

 

with what you're doing its dead easy..All you have to do is add 4 wires:vtec solenoid,vtec pressure switch and ground,knock sensor,and 2nd o2 sensor,then run the wires into the cabin and pin them into the ecu ,there are diagrams all over the net.
