Where can you find a wiring diagram for the fog lamp switch on a 1991 Nissan Pathfiner?

Normally the fog lamp switch (illuminated) has 3 leads: power, accessory, and ground.

[b]Power[/b] is connected to existing power when ignition is "on" or "accessory"

[b]Accessory[/b] goes to the relay (86)

[b]Ground[/b]... goes to a ground.

A non-illuminated switch won't have a ground.

The relay consists of:

(86) - switch

(85) - ground to chassis

(30) - main power to battery (15 or 20 amp fused)

(87) (one or 2) - power to lamps

Hope that helps.
