Installation Notes

Verify the ignition coil style and engine application before installation, especially on 2007 old body style trucks and Classic models. Route the wires to match the original layout and confirm secure terminal engagement at the coil and spark plug ends. The part number 924-6012B should be matched to the vehicle’s listed fitment and ignition configuration.
