2003 ford focus how would you install a new temp gauge from a pillar pod where does the copper end go to?
Not under "normal" conditions. I have made very fine gauge copper wire explode by putting a few thousand amperes through it, but that was not the copper specifically exploding. Any fine gauge wire regardless of what it is made of with that much current passing through it heats rapidly and vaporizes, producing an explosion.
No, number one copper is used in buss bars. "Number one copper" is a term I am familiar with from recycling copper. It does indeed include buss bars, but also includes any solid wire whose insulation has been removed, or large gauge wire with large strands (as opposed to small gauge stranded wire) whose insulation has been removed. -- Sparkfighter
Your best bet would be to go to oreillys or auto zone and get a small gas gauge and unhook the wires from the gauge in your dash and run it to the side and put it by the pillar... I did the same with my temp gauge and it did fine, although if you want it to light up run a power and ground from the stock gauge too and you'll be good to…
