Detailed Description

The DS-1270 is a steering column turn signal switch designed for vehicles that rely on integrated signal and cruise control functions. It is a direct-fit style replacement for select 1988-1993 Pontiac Grand Prix and 1988-1991 Pontiac Tempest applications, including 1988-1990 Pontiac Grand Prix models with cruise control and a single lever multifunction switch assembly.

Verify connector style, terminal count, and vehicle configuration before installation. This switch uses a male connector with female pins and is intended for applications that match the listed Pontiac Grand Prix and Tempest fitment. Confirm whether the vehicle has cruise control and a single lever multifunction switch assembly when applicable. Follow factory service procedures for steering column disassembly, electrical connector inspection, and switch alignment.
