- Sun Mar 04, 2012 2:46 am #296944 ok so im sure this has been asked before but ive been searching pretty hard and cant find the answers i need. heres what i have. 93 civic dx non vtec. swapped in a jdm b16 SIR motor. have the p30 ecu that mates to it. here is my trouble. i have no vtec plug or wiring also the knock sensor above the oil filter has two wires sticking out but dont know where to put them. everything else is plug and play. the motor runs smooth other than lack of vtec power. ive seen diagrams but dont know what plug is called what or which one goes where. thank you guys ahead of time for any help you can give me.

the jdm motors didnt come with a pressure switch for the vtec. also if you are using the non vtec harness then you will need to wire up vtec or get a harness for a vtec motor like the z6 harness or a delso dohc harness.

if you need pictures i can post them

The sensor on the passenger side fire wall would be the map sensor, and it will now be on the tb.

The number 7 hose is the evap sensor and that will need to be hooked up.

LS and B116 throttle bodies are the same size. its either 58mm or 60mm.
