Snap-on Timing light help

Has anyone here got a Snap on Timing light number MT2261A ( the computerized Tach / advance unit ) Mine broke today and I found the cables to the Spark Lead pickup unit had disconnected at the pick up. As usual I took it apart, repaired the cables then forgot how it went together !! Can someone just look and confirm the position of the inductive coil, I guess it sits on one the legs of the "u" piece, but would like to be sure. Pictures would be great help if possible. Thanks Frank
