I have a d16y8 head that im going to swap on my d16y5, ive done some research and it looks like i need a knock sensor wired up? if so how would i do this? and the y5 head has an egr valve, the y8 doesnt, do i need to bypass the wire that connects to the egr valve? if so how would i do this? cause im pretty sure if i just leave it hanging im going to throw a cel. Also, i saw something about the y5 o2 sensor plug is a 7 wire plug and something about switching to a 4 pin connector?

 

anyone?
