Greddy speed cut defender?

I borrowed a greddy speed cut defender that my buddy itwas just laying around his shop does anybody know how to hook it up?I know theres power,ground and 2 signal wires but that pins on an S14 SR ecu do I need to use?I am going to the track this weekend and I am hoping to break into the 12’s and the only way I am going to do it is if I get rid of this damn speed cut.My last trip to the track I would get just about to the line and I would hit it.
