Question for the hive mind. Im putting in some LED dash lights and am going to rig up a bench tester for it so I can make sure my unmarked LEDs are in the correct polarity without having to r/r the dash several times. Seriously, who DOESNT mark polarity on their products (insert angry grumbling rant). Anyway, I THINK the dash and gauges run on 12v but Ive come across plenty of 5v bits over the car as well and dont want to overvolt something. Anyone know for sure if any of the circuits on the miata dash are 5v or if they are all 12? TIA
