What is that you need to know? The starter has a positive connection. You need to know what type of alternator you have  and you need to look at both engine wiring diagrams to see how they are connected.

There are 3 different types of alternators.

Stator, Alternator (Tri Circuit, 9Amp Regulated)

Stator, Alternator (Dual-Circuit)

Stator, Alternator 10, 13, or 16 Amp-Depending on Size of Flywheel Magnets) (Regulated)
