wired in a 12v accessory cig lighter for my gps charger tonight, spliced the pos and neg leads to the tail light wires, using a multimeter i figured out which was + and - on the tail light. Installed the socket in the trunk (just laying there right now). Worked out good, checked with my mm and it's getting 12v. Was puttin the tail back together, checked the voltage one more time and accidently shorted the leads together. Long story short it scared the crap out of me bc all my gauges and lights went out, luckily i found the fuse box and it just blew the fuse, installed spare and it's all good now. My question is, will wiring the cig lighter to the tail light like this cause any problems such as over loading the circuit and blowin fuses all the time. I'm sure it will be fine, but wanted to ask the experts. Sorry for the long post
