ok i got this tachometer from autometer with shift light (atm-3905) and i want to instal it on my 92 camaro,i faced a problem with lights switch i cant remove it and when i reached the wires it was electrical and the wires all tied up and i couldnt seperate them,so can someone please explain to me how to wiring another wires for tachometer?

 

i know it will be hardfor you to understand me but now im soo tired of unbolting all those 7mm nuts and 5mm

 

i have the el cheapo tach, and i just mounted it on the dash pad (mines shot), and have the wires running down the front and behind the plastic peice and hidden inside.
