Which wires go where on a 99 Saturn starter?

Depending on the vehichle, you may only have one wire going to the starter, which would be the positive wire from the battery. In addition to this wire, many vehicles have a wire or pair of wires going to the solenoid housing on the starter. The positive wire is a very thick, heavy wire, which usually will have a loop terminal at the end, which fits over a post on the starter, which has a nut that threads down to secure the positive wire.

Often wire lengths will give you a hint as to where they should be connected, and wires frequently are bent to fit the connections. Be careful if you are guessing on where the solenoid wires connect, because a mistake could fry the solenoid.

In AdditionMany vehicles may have an additional, fairly heavy wire that runs to the same post as the battery. This wire makes its way to the alternator and is the location of the charging system fuseable link.
