Ok guys, thanks upfront for the help. I think I may have made a mistake sometime back by moving these ground wire to this location. I don't think those bolts are actually on solid frame on the firewall. The red wire is an extension of my crankshaft position sensor wire, and the mesh steel braid is the trans ground strap I think. I want to move them to a better location... what are your thoughts on the frame location see zinc bolt by my thumb that I'm using for the engine ground which is part of my big 4 0 gauge upgrade.
