The early GM/FORD generators and externally regulated alternators are just not up to the task of providing power to an expanded wiring system like these classic update kits. The point of this kind of kit is really to allow people a way to upgrade and expand their wiring system and so an alternator upgrade is usually part and parcel to this kind of upgrade.

NOTE: These kits are recommended for MODIFIED original vehicles, not OEM restoration projects.

Note: This wiring is designed to work on Internally regulated alternator and have a 12v feed for the coil/distributor/ignition box. This kit IS NOT set up with a resistance wire for a standard, points type ignition system. It is wired with a full 12 volt primary ignition feed that is hot in both the start and run positions. It will support HEI, MSD, other electronic ignition systems, as well as computerized Fuel Injec- tion systems. If you wish to run a points type system, there are illustrations on the engine connection pages to do so. Extra parts that are not included in this kit will be required to complete that operation.
