need help swaping b16a obd0 into 93 honda del sol

I'm a newbie when comes to engine swap. I put the b16 in but the mount doesn't fit and the harness plug does not plug up.....the plug are totally different. Can some one please tell me which part of the harness I need to convert or list down step by step what I need and what to do. Basically teach me from A-Z. I don't want to let my motor set out in the cold for long.
