I'm looking for a 92-95 accord for an h22 swap have some questions even though it looks pretty straight-forward: 1. Is there any difference between the 92-93's and the 94-95's? 2. I'm planning on buying this complete changeover: http://www.hmotorsonline.com/shop/sc2000search.cgi?what=page&item=30017 does this have everything I will need? 3. Should I get this rywire harness will it be necessary? : Rywire : OBD1 & OBD2 VTEC Subharness - $55.00 4. Can I keep the p/s and a/c from the f22?
