Can anybody tell me what important things that are needed to be hooked up for my crx to pass a smog ref????the engine is from a 96 ls integra and i just used my old si harness and used a PR4 ecu. Any suggestions will be a great help....

 

I believe all of the orginal smog equipment from your old motor. Refs look for everything that needs to be hooked up and since your motor is a 96, they'll look for two 02 senors that should be hooked up, matchin Ls ECU, and all of the smog equipment from the 96 LS should be hooked up on your new motor. If you have mods make sure they have CARB EO # because they do run them through and also paperwork for your motor because they too run the numbers through your motor as well. Oh yea, you need to make sure the stock LS fuel system is on there too, like the stock fuel rail and pressure regulator as well. And you have to pass the smog test as well to get the BAR sticker. Hope this helps.
