Visit me at: http://www.ericthecarguy.com/ Visit PowerProbe http://www.powerprobe.com/powerprobe/Home.html I broke out the Power Probe again to help diagnose why my dome light wasn't working, I think this tool is perfect for something like this as it is a 12v circuit. It's a good idea to get your hands on a good wiring diagram when you're working on something like this, here's a source that might help you. http://www.bbbind.com/tech_database.html Stay dirty ETCC Due to factors beyond the control of EricTheCarGuy, it cannot guarantee against unauthorized modifications of this information, or improper use of this information.
