i have recently swapped muh d15b8 to a d15z1 ( 92 vx engine ) , on the vx engine there is a ''egr valve'' on the intake manifold right behind the vtec soliniod, it came with a egr pump and egr soliniod, in a little black box thing, there's a plug on the egr valve and i have no idea were it goes? do i need this to start the motor?

ALSO, i have a 94 cx, meaning i have a 1 wire o2 sensor. the motor is a 5 wire sensor. do i need to convert to be able to start the engine? i am totally cluelless. any help will be MUCH appreciated!
