I have the sensor in the exhaust and the module in my ash tray. I just don't know how to wire it now. What ignition source do you hook it up to? Does the black ground go right to the battery? How do you wire it to the battery cable? What do you use for a power source? Do you go off the fuse box? I'm a dumby with electrical stuff. Any help would be greatly appreciated. The PLX instruction sheet isn't detailed enough for me. Thanks, Chad
