Installation Notes and Tips

Verify wire routing against the original layout before installation, especially on the Toyota Land Cruiser where angled and straight boot positions matter. Match each lead to the correct cylinder and terminal location, and inspect the distributor cap, coil connection, and spark plugs for wear before installing the new set. Confirm the 7mm specification and terminal style match the vehicle’s original ignition setup.
