Looking for the diagram that will give me a better understanding of this system. Also looking for the manual that will give me the specs for adjustment of the cables. Thanks

Your drive is a Alpha GEN II and uses Manual 14 . Shift interupt for alpha is either a ground to the ign coil or 12 to the electronics to cause the motor to "stumble" to alllow you to come out of gear. Being a MPI computer controlled it applies 12 to the computer to cause a stumble. Manual for the engine should be number 24
