"I have a 93 mega 25 that i want to hook a tach up to. The local dealer sold me a faria tach, and told me the signal wire is the yellow wire coming from the rectifier. i spliced it in here followed all the instructions that came with the tach.. nothing the needle doesnt move.. is this the correct signal wire? what rpms should i be turning? 5500-5700?"

Chances are the tach will never work. Faria tachs lack an additional diode to catch the pulse signal. take it back and get the factory tach. Everything is color coded and your service manual will have all of the specifications in it.
