Hook it up as if it were an SI..
1988 model:

1991 model:


If an Si doesn't have it,You really don't need it..
Plug any open vacuum connections and move on..

basically what you want to do is take the hf's box,egr valve and its vacuum lines and remove all that **** completly...then just proceed to hook it up like a stock si d16a6..

The only things that matter anyway is map sensor,fuel pressure regulator and brake booster vacuum lines.
