S130Z Posted November 15, 2009 Share Posted November 15, 2009 So after searching high and low, and trying multiple combinations of wiring, I am at a total loss. I am running MS II 3.57 with the coil driver installed. I am running the stock turbo ignition with MSD Blaster Coil(if that makes a difference). My problem is I am getting no tach signal to MS or my tach. I have my factory wiring harness in my 83 ZX removed. As I read, you must connect the blue wire comming from the coil back to the resistor inside the cab. I have done this and got no signal. Any help is greatly appreciated.

S130Z Posted November 16, 2009 Author Share Posted November 16, 2009 I figured it out guys. My shielded wire from MS was grounding out the voltage signal because the shielding was touching my soldered point. I hope this helps anyone in the future.
