i have a 2002 pontiac sunfire where is my ground wire located? what does it look like?
There is ground wire that connects the battery's negatime post to the frame of the car and that is it. If you are looking for a ground wire to connect something to eg. an amp, just connect the ground from the electronic device to the frame of your car via a bolt that goes in to your cars chassis/frame.
Have a look at the battery. The wire ( usually black about 3/8th inch thick ) on the negative ( -ve ) terminal is connected to the inner wing / chassis or 'ground'. Various components - gearbox etc use a braided wire strap to ground as ordinary wire will break due to vibration. The red wire ( +ve ) goes to the alternator then into the various fuse distribution boxes
