Outlaw

I'm swappin a 2000 h22a4 into my 97 CL, and I'm plannin on stayin OBD2 for now so I can get that BAR sticker. The junkyard dealer (Import Auto in Hayward, CA) I got the engine from didn't have the wire harness on him at the time and said he would call me up when he had it. Later on, he calls me and tells me that he called around a couple of shops and they told him that using the CL harness is fine by itself, and that I didn't need the h22 harness. I asked Mark Davison about it, and he said that I need to add some plugs from the h22 harness. Now, which ones do I need to add and why? I need to know so I can let this punk ass dealer know that I need the damn thing. Thanks.
