So is it ok to leave the factory amp gauge hooked up?I see in the diagram it is.I have heard that the connection at the bulkhead connector and the amp gauge couldn't handle that may amps?Or is it OK because you have another wire going to the battery also?

The way that is wired it effectivily bypasses the factory amp guage, which is a must on any alternator upgrade, the factory wiring and bulkhead connector will not tollerate any of these late model higher output alternators for even a short time.
That diagram was done that way (keeping existing wire to alternator) so as not to hack up a factory harness for those that may want a better charging system, but have the option to return everything to stock with little effort.
