One of my bestfriends just did the 1zz to 2zz swap and everything works fine except his headlights and his gauges. His speedometer and his tachometer wont move. The lights in his gauge cluster work, and all the little warning lights work, alont with the temp gauge and the gas gauge. His headlights also dont wotk. The only way we can get them to work is put a ground wire to his headlight relay and he has to ground it everytime he drives at night and take it off when he gets out. We took everything apart, and put it back together and still the same problem. A mechanic did the same thing. Do anyone know if an ecu would or could cause these problems???????
