We then mounted the coil to the firewall in a location close to thedistributor. Crane recommends the coil be mounted within 18 inches ofthe distributor. Also, the mounting bracket for the coil must begrounded. Since we were mounting it to the firewall, this was not anissue. If you mount the coil to a fiberglass, wood, or plastic mountingpoint, run a ground wire from the coil bracket to a grounding source.
