Love the forum guys!! Lots of good info and already starting to do many upgrades I've read about here. I am having the "flickering lights" issue and after reading about it, started the process of locating and cleaning the ground wire connections, to see if that helps. I traced the negative battery cable and found the connection to the engine block (the easy one). I have not been able to find the other locations, and wondered if anyone has any info/pictures on their location? I tried to trace a second wire and lose it where it appears to be heading into the front bumper. Any help would be greatly appreciated, and hopefully keep me from tearing the entire front end apart trying to find them.
