I looked in the 92 service manual but it doesn't say much other than the thing just pulls out. Here's what the manual says: HEADLAMP SWITCH/TWILIGHT SENTINEL/DAYLIGHT LAMPS MODULE Removal or Disconnect 1. Headlamp switch module from the I/P by firmly pulling outward on headlamp knob. 2. Electrical connector from back of headlamp switch. Install or Connect 1. Electrical connector to back of headlamp switch. 2. Headlamp switch to I/P by gently pushing into place.
