Ok..........we are putting a jdm d15b vtec engine in my 90 crx dx converted to mpfi with a pr3 ecu. What wires are needed to run to setup up good ol vtec. I plan on gettin a vtec controller soon to adjust the fuel flow and activation point but do i need one now?
 
How do I run VTEC for obd0???? Can i jut run it from the VTEC controller to the ecu etc... Or am I way off??? Please help.
