Wanted brighter lights, tried Silverstars and others. Silverstars were whiter but did not throw longer or wider, just whiter. Finally installed Slee's upgrade harness and a set of low and high HIR's. Fantastic! Just what I had hoped for. Now the fkup. Cost me $300. to find this out. I grounded the wires on the slee harness and left the grounds on the original harness tucked away. My truck stalled to the point I thought it was a fuel pump or MAS. Would crank but not fire, towed it, got to destination and it cranked and fired, ran smooth as silk. No codes turned up, could not replicate. Took it to my Indie mechanic, same thing, then to Toyota, same thing, then to Lexus. Tech checked the wiring diagram and found the grounds were tied somehow to the fuel regulator or something like that. One $100. tow, one $85. troubleshoot and one $115. trip to Lexus to hook up two ground wires later it is fixed. Obviously I'm not the most well versed at this stuff but at least I'm trying. Learn by my mistakes all you noobies!
