So i'm swapping in a obd2 ls into my '94 si. all my questions have been answered except the wiring.
I do NOT want to convert to obd2 as i will want the obd1 later for turbo.
Injectors: will i need a resistor box?
Distributor: can i splice those? or do i need to find and obd1?
Vtec: my wiring harness is a vtec one. do i just de-pin the vtec wires for the new ecu?
ECU: will a obd1 ecu be the best choice? (what the ecu doesn't see doesn't matter?) aka 2nd o2 sensor?
jumper harness = obd2 ecu right?

thanks in advance i cant wait to get started putting the new motor in.

Use a '96 - '01 Integra harness (ideally a '96 - '99 as the '00 - '01 version has to have the tach wire added) and an OBD1 LS ECU. Thats it, no cutting, no splicing, no conversion harnesses.

You will need a resistor box whenever you go turbo and swap injectors. But not for running the stock injectors. Also you don't need to depin vtec wiring.

k thanks thats exactly what i wanted to know. just incase limited fundage or lack of resonable availability has any one tried to use the civic harness.

any ways i'm going to the junk yard tomorrow hopefully i'll find what i'm looking for

Otherwise your si harness will plug and play. Some people claim you need to lengthan some wires but I've never had too. I'm sure they sell dizzy jumper harness for obd2 to obd1 but you can just depin the obd2 to a obd1 connecter. I advise depin and repining one at a time. If there not color coded you can pull the cap and see which wires go to which terminal of ign coil ect ect. GL

thanks i have lots of time so i'll se what works best , i might want to keep my Si harness intact incase i or any one ever needs it.
thanks for the answers people.
