alright....got a question here....i just picked up a 91 DA with LSvtec, but the guy never hooked up the vtec.....i looked around for the knock sensor and i see none....i saw that in one of the threads that you have to thread a new hole for the knock sensor, but if you run a line to the ecu what do you do with pressure oil switch wire? any one with experinece please help

 

pm katman or email kenji they can both help u

 

b19 is the knock sensor hook up...
b5 is the vtec pressure switch hook up...
a8 is the vtec solenoid hook up...
c8 is the 2nd o2 sensor hook up...
i hope this helps out.. if you get confused, IM me, and i'll give you the schematic..
