If i want my tach to light up when i turn my panel lights on, which fuse should i run the power to? Or what wire should i splice into? and also, where should i put the power to the shift light? Thanks
Fuse 13 is the dimmer fuse. The fuse is after the dimmer, so you can tap right into the fuse with a fuse tap. You can also tap into the circuit behind the fuse box or any place that has dimmed lighting (HVAC controls, etc).
Key-on power is something that can be grabbed whereever is convenient with regard to your mounting location.
