The supplier calls it a general wiring harness for fog lamp modification. The photos show a relay with a mounting tab, an inline blade fuse holder, a rocker switch with a fog lamp symbol, two sealed lamp plugs and ring terminals for the battery and earth. Easy Life Markets sells it as one complete harness.\u003c\/p\u003e\n\n\u003cp\u003eFog lamps draw more current than a dashboard switch should carry on its own. That is why a proper installation uses a \u003ca href=\"https:\/\/en.wikipedia.org\/wiki\/Relay\" target=\"_blank\" rel=\"noopener\"\u003erelay\u003c\/a\u003e: the switch only has to wake the relay up, and the relay passes battery power to the lamps through a fused feed. Building that circuit from loose wire, crimp terminals and a relay socket takes time and leaves plenty of room for mistakes. A pre-assembled loom has the relay, fuse and plugs already joined, so the work is mostly routing and connecting.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You Get\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 x fog lamp harness, with the relay, fuse holder and switch attached as shown in the photos\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFog lamps, bulbs, mounting brackets and instructions are not listed as included.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct type:\u003c\/strong\u003e Wiring harness for front fog lamps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductor material:\u003c\/strong\u003e Copper wire\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLamp connections:\u003c\/strong\u003e Two sealed plugs, one for each lamp, as shown in the photos\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl:\u003c\/strong\u003e Rocker switch with fog lamp symbol and indicator window\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection:\u003c\/strong\u003e Inline blade fuse holder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize given by the supplier:\u003c\/strong\u003e 5 x 2.4 x 4.9 cm.

The ring terminals go to the battery positive and to a good earth. The fused feed runs to the relay. The switch lead passes through the bulkhead into the cabin, and the two lamp plugs run forward to the bumper. When you press the switch, the relay closes and both lamps light. Many installers take the switch feed from a circuit that is only live with the side lights or ignition on, so the fog lamps cannot be left on by accident. Check the rules where you drive as well. Many places set out when front fog lamps may be used and how they must be wired.\u003c\/p\u003e\n\n\u003ch2\u003eFitting Tips\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDisconnect the battery before you start.\u003c\/li\u003e\n\u003cli\u003eMount the relay with its terminals pointing down, somewhere away from direct spray and exhaust heat.\u003c\/li\u003e\n\u003cli\u003eKeep the fuse holder close to the battery end of the feed, where you can reach it.\u003c\/li\u003e\n\u003cli\u003eUse an existing rubber grommet to pass the switch lead through the bulkhead.
