2005 Used Manual Gasoline Quarter 2005 Muscat Lexus. It had a 400 engine and it broke down, so I installed a 430 engine. After installing it, the computer for the 400 doesn't fit. Currently, only the wiring harness for the installed engine is present, but it needs a computer. I found one for 600. The old 400 engine and its wiring harness are available and working. The transfer case shaft is disconnected. The engine is strong. I changed the front and rear differentials to petrol. The car is nice and has been repainted.
