Im kind of a noob when it comes to wires, i understand basics, but dont ask me to wire up a 3 phase motor or a washing machine.
My car is a 94 aspire 5 speed, and my tach has 3 wires, one red, one black, one green.
Green goes to distributor wire, im splicing it to the existing rpm tach wire in the cluster.
Black is ground
Red is power.
Now, I have a "smoke" lens so it needs juice all the time, but i want to be able to dim it, so i want to hook it up to the stock dimmer switch.
I did a little research, am i to understand the lights in the car are on a neutral trigger, and if i splice the red wire to the instrument cluster illumination wire and add a ground after the gauge to the chassy, the gauge will be powered anytime the car is on, and be dimmable?
To my understanding, the switch on the steering column grounds the circuit causing juice to flow, so if i grounded the gauge to the chassy it would come on right?
I am planning on cutting that whole illumination wire out of the cluster because i run led lights to it anyway.
