ELIJAH EG-2

So I am currently swaping a 98 GSR into my 95 civic. I am using the 98 USDM harness, my question is on the passenger side (right side for us americans) the 3 shocktower connectors the two big ones and the one little one wich I am talking about now is a small oval/rectangular shape. Now on the engine harness it is a 3 pin to where my EJ has a four pin. The two big ones connect together just fine and all that. but can someone help me idenify the wires to as what they are and what they do on both sides. Sorry I dont have the colors availible with me at this time. This would be a great help to me right now. I hope to see some O.G. Honda-Tech people reply back with helpfull info. Thank you and have a great day. " Note-I am using a P72 obd1 ecu"
