Does anybody know what the white electrical connector is for? I believe the blue one is for the clock but I cant seem to locate the white connector in the FSM. This is on a 1990 Box Truck (U-Haul).

 

The clock should have a 4-pin inline connector (like the white one you show), and blue-yellow, white-black, green, and gray-red wires.

The blue connector is the shape of the "power outlet" (cigarette lighter) connector. Only 2 pins (2, 4) are active.

While generally a "picture is worth 1000 words," for electrical connectors pictures really are almost worthless. The connector forms are consistent through years, but the colors of the connector bodies are not. What IS useful is the wire colors. Several on this forum have an EWD; if you give all four wire colors (in order) they may be able to help.

 

That blue 4 pin is the same as the clock connector in my 4Runner.

If I recall correctly, the white one looks like either hazard lights or rear defroster switch. I assume rear defrost is 4Runner only though.

Edit: The white one seems to be the wrong color (should be orange) and wrong pin count to be the hazard lights according to my 95 FSM.
