Having problems with your 1997 GMC Sierra ?
I need the starter wiring diagram
\015 I need to know where the small wire leads to\015
In the starter you have the B+ terminal which is power from the battery. The other big gauge wire which goes from the solenoid to the actual starter motor supplies power to the motor once the solenoid switch makes contact during cranking. The other wire the smaller gauge wire is power from the ignition switch. The starter grounds through its case. Hope this helps.
