I'm adding a 68-74 console with 4 gauge pod to my 62. I'm using Autometer Phantom 2 1/16 short sweep electrical oil pressure, water temp, voltmeter and a clock. The first 3 all require a 12v switched input. Can I daisy chain those gauges together and feed just one an 18 gauge wire? 18 gauge is what the instructions call for for power and ground. Seems light to me and maybe more so if daisy chained. I also would like to wire all grounds (gauge and lights) together and use one 18 gauge wire out to the engine block. I plan to get power from the fuse panel male spade connector marked ACC and CLK.
