i need a wire that will only supply power when the headlights come on so that it isnt illuminated all of the time (i.e. the day)ej20fan said:thingys....read Multimeter or test light.
No need to cut. You only need to probe the wire, not strip the insulation.The ghetto solution is to wrap the wire around the fuse. Make sure it's on the fused side of it. The one that does not have power when fuse is pulled out/blown.
The best way is to run a wire from the battery, use a relay and then use the headlight fuse/wire as a trigger for the relay to switch and pass 12v+ to the gauge.
Hence the relay. It is a trigger for the light to turn on in your gauges. This way, you'll never encounter a problem, or fuse flambeau. The gauges will only light up when the headlights are turned on, furthmore, you'll never have to worry about any kind of powersurge/spike frying "5" things instead of one.justboosted02 said:i need a wire that will only supply power when the headlights come on so that it isnt illuminated all of the time (i.e. the day)
