tach stopped working

[wondersb]

Hi all. This fall I parked my car and started putting all my new toys on it. One of the things that I did was put some colored wire looming in the engine compartment. when I finished I started it up and my tack did not work. I am thinking I must have broke a wire some where. My question is were dose the tack get the signal from the engine? It would save me a lot of time ripping it all apart again. thanks

first place i would start is the CAS. that is where the signal initiates from. after that try the power transistor.after that i would make sure you have a complete circuit from the ECU to the CAS. if that doesnt help them PM me and i will try to Help as much as possible. let me know how it goesgood luck
