As some of you know im putting a 98 D16Y7 into my 93 delsol. but what i had to do to make this work was exchange the D15B7 airintake manifold an put it on the D16Y7 motor. after i had put that on i realized that there are 2 vacum hoses that have nowheres to go. on the back of the motor there is a black box under the intake manifold, but on the bottom of the D16 intake manifold are 2 nipples where the vacum lines go to but with the D15 intake manifold there isnt those 2 nipples to put the vacum lines on, where do these 2 vacum lines that come from that black box go to ?
