on the back of the b18 beside the alternator there are 2 sensors that screw into the block on the d15 there is only one what are the sensors.... what do i have to do to hook them both up

1 of them is probably a knock sensor the other I believe is an oil sensor. you don't have to have the knock sensor hooked up for the car to run
