Hello to all. relatively new cruiser owner, 74 FJ40 with a refurbished rhino lined tub from 68, stock. "Hella" problems on getting these 500's to work. Read all searched posts on wiring these, have the green wire spliced into hot fuse instead of headlight wire. Read postings on negative charged systems so upon advice of archived posts took my blue ground into positive lead on battery and still no lights. Am I missing something here? Should the ground on swtich go to something other than a real ground? Any FJ40 owners put these on there and how? All responses appreciated, Brian
