Whichever alt you use the best way to wire it is to use the later harness 124 543 45 26. The difference between the early alt and the later in the hook-up is the output terminals screw on the hi outout alternators.
Unless you can aquire 8mm ID eye terminals of proper stature and solder them in you will be using up connectors with the high output.
