Easy to install with a few minor mounting bracket substitutions/modifications. Wiring is easy to do after identifying + battery cable(s) and alternator indicator lamp lead. Functions without having to use ignition switch to turn on.
Had to do a little modifying to my alternator bracket as this is a large case and it will not clear the cylinder head otherwise, but that's part of hot-rodding. Works great, charges 14.5 at idle.
