 | I just purchased a Lowrance X-87 and am installing it in my boat.  This particular model comes with a temperature sensor built into the transducer.  I also ordered the speed sensor (SP-X) with it.   I also have the split cable (MY-4X) to attach the transducer and speed cables to the unit. 
 The SP-X speed sensor cable splits.  One end is connected to the speed sensor, one end is attacheds to the MY-4X cable (which is attached to the main unit) and the other connector, not sure (there's nothing to attach it to).  No additional temperature sensors came with it.
 
 Two Questions:  What does the other connector attach to?  Another temp sensor?  Can it not be attached at all and the speed sensor still works?
 
 One more question:  If I don't use the MY-4X cable and not the speed sensor, can I attach the transducer cable directly to the unit?
