Detailed Description

Standard Ignition DS-989 is engineered as a combination switch for lighting and directional signal control. It includes main light operator, latching high beam operator, momentary high beam flasher, and turn signal functions, while omitting cruise control, fog light, washer, and rear wiper controls. That makes it a focused replacement for vehicles equipped with the matching switch layout.

This part cross-references CS605 and DL6331 for the same application. It is listed for 2001-2004 Jeep TJ, 2001-2004 Jeep Wrangler, 2005-2006 Jeep TJ, 2001-2002 Jeep TJ, 2001-2003 Jeep Wrangler, 2005 Jeep Wrangler, and 2006 Jeep Wrangler, with notes specifying use on vehicles without fog lights. If you are replacing a worn Jeep TJ headlight dimmer switch or a Jeep Wrangler combination switch assembly, DS-989 provides the required lighting and turn signal control in one unit.

What This Part Helps Resolve

• Intermittent or failed headlight dimmer operation
• High beam switch issues, including flash-to-pass or latching function problems
• Turn signal control faults at the steering column switch
• Worn or damaged combination switch electrical contacts
• Lighting control problems on Jeep TJ and Wrangler models without fog lights

Installation Notes and Tips

Verify connector shape, terminal count, and switch layout before installation. This part uses a bolt-on attachment method and a single rectangular female connector, so matching the original column switch configuration is important. Confirm that the vehicle is not equipped with fog lights, since the fitment notes exclude those applications.

For best results, compare the original switch functions to the replacement unit before removal. Standard Ignition DS-989 is intended for direct replacement use on the listed Jeep TJ and Wrangler applications with the correct non-fog-light configuration.

Quality Assurance

Standard Ignition states that this switch is built with robust materials, copper alloy conductors, and 100% testing for both mechanical and electrical switching performance. Those checks support consistent operation in service environments where lighting and signal control must work reliably.
