Installation Notes and Tips

Verify engine configuration and ignition system type before installation, especially on 1973-1974 Buick models noted without HEI. Match each wire to the correct cylinder and coil/distributor terminal location, and route the wires to avoid contact with exhaust components or sharp edges. Confirm the 7mm specification and terminal style against the removed part before final installation.
