I purchased a accupart light switch several months ago. Yesterday I asked if you had a wiring diagram and could you text me a copy
Omix 17234.04 (equivalent to OE 5751098) doesn't include a diagram in the box; it follows the standard 7-terminal layout used for 1979–1986 Jeep CJs.
Below is the terminal pinout and wiring guide to help you get your lights back on.
Terminal Pinout Guide
The terminals are usually arranged in a semi-circle or "U" shape on the back of the switch. If you look at the back of the switch with the rheostat (the ceramic coil) at the top, the pins generally function as follows:
Terminal Label // Typical Wire Color // Function
B1 // Red // Battery Power (Fused) - Constant power for headlights.
B2 // Red w/ White Trace // Battery Power (Unfused/Fusible Link) - Power for parking/tail/dash.
H // Blue // Headlight Output - Goes to the Floor Dimmer Switch.
P // White // Parking Lights - Front parking and side marker lamps.
R // Black // Rear/Tail Lights - Rear tail light circuit.
I // Orange // Instrument Panel - Dimmable dash lights (controlled by turning knob).
D // Black w/ White Trace // Dome Light - Ground trigger for interior lights (activated by turning knob fully).Installation
Pro-Tips
The "Secret" Button: To install or remove the knob/shaft, there is a small spring-loaded button on the body of the switch (usually on the opposite side of the terminals). Pull the knob to the "ON" position, depress the button, and pull the shaft completely out.
Check the Ground: The switch body itself often needs to be grounded to the metal dash for the dome light circuit to work correctly. If your dash is painted or rusty, you may need to scrape a small amount of paint away behind the mounting nut.
Dimmer Switch Note: If your headlights aren't working but your parking lights are, the issue is often actually the floor-mounted dimmer switch, not the dash switch. Power goes from the Omix switch (Blue wire) to the floor, then splits to high/low beams.
Heat Warning: If your switch gets hot to the touch or your lights flicker, it’s a sign that your factory wiring is drawing too much current. Many Jeep owners install a relay kit to take the heavy electrical load off this switch, which makes the headlights brighter and prevents the switch from melting.

Is there headlight thermal circuit breaker built into this switch?
No. If you need a headlight switch with a built-in thermal circuit breaker for a Jeep TJ, the OMIX 17234.04 designed for older CJ models is likely not the correct part. You would need to look for a switch specifically designed for the TJ and check its features.

Does this come with the bezel that goes on the dash board?
No, they do not. We do offer them as well though. See the following link. Omix Switch Bezel 17234.12 Thanks for your inquiry.

Where can I find the center post that connect this to the knob?
The knob has the center post attached to it and can be viewed in the following link. Knob with rod for Headlight on/off Thanks for your inquiry.
