Just curious what every one is doing with the plug and play kits for the HID Fogs. Plug and Play? Plug and Play with a 15/20amp fuse? Or buy the battery relay?

I've read lots of different threads and was having trouble finding what Im looking for between them.

To help clairify all of this...

All PnP (Plug and Play) means is that it is supposed to work by just "plugging it in". Serious.

It is recommended that you change the headlight fuse from 10 to 20 amp if you are upgrading those. Some have blown the 10 amp fuses. I don't think I needed to change the foglight fuse when I went toHIDs.

You don't need a relay for the foglights. Only the headlights do.

The relay (actually its coil resistance) is used and attached to a harness to "fool" the headlight system. The stock bulbs exhibits ~55 ohms of resistance (load) to the system. If the system detects a different resistance it thinks a light is out or shorted and won't close either one side or both. HIDs ballasts have a lower resistance (~33 ohms). Hence the problems. The coil resistance (~55 ohms ) of the relay is the first thing the system sees and it thinks everything is working fine and stock. An updated version of this is a series resistor that can be installed intead of the relay harness.

The stock foglight housings are already projector type

Hope that helps.

Battery harness relay with inline fuse will promote the longevity life of your ballasts! I only installed one of these for my headlights,no need for the fogs!

I did not have to do anything for my HID fogs but plug everything in.

HID fogs are incredible compared to the 37.5W stock bulb or the 50W upgrade.

I simply plugged mine in (been over a year, easy), and have had no issues with fuses or anything else.
