ok, swapped a jdm b18c 98' itr into my 96' LS non-vtec.. Been drivin it w/o VTEC. Having wiring complications for the most part. But I just found out that my jdm doesn't come with a pressure switch. I'm using the p73 ECU that it came with.... now.... Please, will someone help me out with what I have to do to get this VTEC kickin in. I've looked all over the www. no dice. I would be so greatful and appeciate any help. Thank you.

 

the pressure switch is built in the jdm ecu. did you already try wiring the vtec straight to the ecu??

 

what wiring harness are you using?

 

whatever it all came with. i assumed everything shouldve been plug and play, but since my LS was a non-vtec i'm not sure what to do

 

if you are using your stock ls wiring harness you need to get it wired up for vtec.
