I am installing an autometer monster tach, and I have a question...
Do I plan to run a wire through the firewall to get to the coil signal negative, or can I tap this from somewhere in the dash?
Can't I just tap it off whatever signal is sent to the stock in-dash tachometer?
Thanks in advance for your help.
Also what about the physical mounting? I want minimal damage to the interior, I am planning on drilling two holes on the side of the center consol dash cover (hard plastic) and fixing it there so it hangs right over the center vents. Any comments?
You can tap into the gauge feed at the back of the gauges. Should be a dark green/yellow wire if I remember right. But just check the wire at the negative side of the coil, and match it to the correct wire at the gauges.
