How to install the headlight dimmer switch assembly and related components in a steering column on Toyota Tundra?

Put the headlight dimmer switch assembly onto the steering column while ensuring the switch protrusions connect with the shaft cutout parts and loosen the band clamp before attaching the claw to lock the assembly and attach the connector. The second step involves fitting the claw that allows the windshield wiper switch connection and connector attachment. Install first the spiral cable sub-assembly then align it with the tilt and telescopic manual switch for powering up the steering column with tilt and telescopic capabilities. The installation process begins with applying the upper steering column cover to manual tilt models before proceeding with manual tilt and manual telescopic steering column models and completing with power tilt and power telescopic steering column models. You should install the lower steering column cover starting with manual tilt adjustment and then moving to manual tilt and manual telescopic control and finishing with power tilt and power telescopic steering column configuration. After installing the magnetic assembly of the steering wheel the technician should apply the steering pad which contains the switch followed by the pad alone. The installation order includes attaching the lower No. 3 steering wheel cover followed by installing the lower No. 2 steering wheel cover. After putting the cable onto the negative battery terminal users should note that initialization steps might be needed for certain systems before restarting. It is essential to examine the SRS warning light for appropriate system operations after reconnection.

How to remove the dimmer switch on Toyota Tundra?
