Help Please Altenator questions

[tphsmith]

I have a 72 fleetside, the engine is a 1994 LT1, runs good, I have not run it to break in the motor yet, (waiting for this cold snap to move on) but I have the altenator wired as follows, the alt. battery post going to the battery. then there is a harness on the Alt from the LT1 wire harness. this harness has 1 wire connected for the plug. What my worry is looking in the 72 service manualin the electrical Body and Chassis section I see a fused wire 14 gage Black and white wire that is spiced into the unfused power wire going to the fuse block. this wire that is fused if I'm seeing this right should this wire be connected to the B+ post wire thats on my Alt.?

and also do I have the Alt connected correctly with just the LT1 harness connector and the Battery wire connected to the batt. is this all I need?

I have not run the engine long enough to see if it charges the battery, also I dont know how to check that if I am to be honest about this all

Please help me out to understand what I need Please
