i have a ek non vtec and i bought an ex mani for it but it came off an automatic the iacv plug on automatics are 3 wires and on manuals are 2. my lx is also a 3 wire plug But its manual,i dont know if is a plug and play. iwas reading that when u do such of swap u need to do a pin out on ecu by moving the a14 to the a12 spot and disconect a13 orange one and than wire my 3 way plug to the ex 2 wire mani. but like i said thats for manual intake mani , automatic ones have 3 wires just like mines.

 

I would recommend using the 2 wire iacv setup if your car is a 5 speed.
If your car is an automatic use a 3 wire iacv.

 

Oh ok so it means i could replace that 3 wire iacv plug that came with automatic mani with the manual 2 wire plug and than cut off my 3 wire plug thats on my car and rewire and do the pin out thing on the ecu, thanks
