What does the number 14 wire go to on a 1992 Sunbird 4 cylinder starter?

What colour is the wire?

There do not appear to be any wires coming from the starter motor itself, here's what goes to the solenoid:

PPL - From Transaxle Position Switch (AT) or the Clutch Start Switch (MT)

BLK - Ground from battery

BLU - Through fusable link C to coolant fans

RUST - Through fusable link B to charging system and HVAC blower controls (probably through the high-blower relay at the back right of the engine; beside the fuel pump relay).
