there should be one big outlet and one little outlet on the intake tube. you can either drill a hole into your intake tube and jb weld some outlet to connect the intake tube to, or go to an auto parts store and try to find some kind of "t" to connect to the intake so you can run two hoses to the one outlet. i had to do the same thing on my 90 teg, i jb welded a fitting that was on the stock intake ducting.

on a side note, how do you like the hatch running with the b18a? i have an 88 hatch that im working on right now, im either gonna sell my teg and buy some sort of d series and boost it, or swap my tegs b18 into the hatch. it just depends on if someone buys my car before im ready to swap, probably in a month or two. anyways, good luck.
