Installation Notes and Tips

Verify the vehicle year and engine application before installation. Route each wire to match the original layout on the Toyota Previa to avoid crossfire and contact with hot or moving components. Inspect spark plugs, distributor cap, and ignition coil condition at the same time, since worn ignition parts can affect wire performance. Confirm the RC-TX71 / 4446 reference before final fitment.
