I am installing an aux gauge cluster made by autometer. I understand that each gauge has its own sender and ground, but there is a gauge power and power for the lights on the gauges, is there any reason that I can't make a three way splice for illumination power and tap a single source wire? I assume I should tap something in the dash light circuit rather than just an ignition hot wire unless I want the lights on all of the time. Would it be OK to tap a main guage illumination wire, or should I tap something like a parking/running light in the main lighting harness. I may be overthinking this, but I am an electrical idiot, as prior posts have indicated. Thanks in advance for your help.
