Wiring Dash Indicators

Here's a quick follow up post to our inDASH video...

A common question that we get about wiring your dash board and gauges is how to wire the turn-signal and high-beam indicators. 

The easiest way to do this is to splice off of the POWERCELL outputs for the turn-signals and high-beam and connect this to the indicators on the dash.  Whether you are using incandescant bulbs or LED's for the indicators, they draw very little current.  You can use a 22-AWG wire with no issues. 

We used two green LED's for the turn-signal indicators.  The LED's can carry a maximum of 30 milliamps so we soldered a limiting resistor in series.  Using a little simple math (V=IR) and assuming that the maximum voltage from the alternator is 14.5 volts, we soldered a 500 ohm resistor in series.  We checked the brightness of the bulb off of the battery to check before we buttoned it up.  We did the same thing for the blue LED that we used for the high-beam indicator.
