the cas on my second gen 13b nt has 4 wires coming out of it, if i want to hook an msd were do i go?, if i use 3 msd, 1 for leading 2 for trailing, the cas controls 3 circuits, 1 leading and 2 independant trailing circuits, but there is just 4 wires and 2 trigger wheels, so what control 2 independant trailing? i look in the archives and there is a lot of diff. answers. thanks

 

What MSD are you trying to use?

Either way, you DO NOT use the CAS outputs as a trigger for anything other than the ECU
Most of their products use a Tach input, of whice you can find on on the coils. There will be a black bullet type connector
