the easiest way i found for the install is to mount your fog lights and ground the ground wire to the chassis. the hot wire(power) you can run to your stock low beam wires (on BOTH sides) this draws the power from each of your low beams to power the fog lights also.

Do you need a relay for fog lights?

Relays are an important component in wiring fog or driving lights with a 30-60A draw. Basically, the relay protects the switch from getting hot and creating unwanted resistance. The low current through the switch triggers the relay to make a higher current connection to the heavy load of the fog lights.

Where do you connect the power wire for fog lights?

Connect them to the matching black ground wires running out of the back of the fog lights, then connect them to an unpainted section of the vehicle frame. Connect (white) power wires together with the matching (white) power wires from each light.

Can I Wire spotlights without a relay?

If your spotlight did not come with an electrical relay, you will need to install one. Most stoplights should not be wired directly to a power source without being run through a relay. If your kit did not come with one, purchase a SPST (Single Pole Single Throw) Relay from your local auto parts store.

How do you wire fog lights with a relay?

1:273:12How to Wire Relay Fog Lights - YouTubeYouTubeStart of suggested clipEnd of suggested clipThough the fuse and two terminal 30 of the relay. The other side of the contacts. Or terminal 87 isMoreThough the fuse and two terminal 30 of the relay. The other side of the contacts. Or terminal 87 is connected right to one of the fog light terminal. The other side of the light is grounded.

How many amps do fog lights use?

The formula is Current (amps) = Power (watts) / Voltage (volts). The fuse on the fog lights is rated at 15 amps.

What gauge wire should I use for fog lights?

Connect the fog lights to terminal 86 using 14-gauge wire.

Does a relay need to be grounded?

The relay must be on the ground side of the load when the voltages above the coil are hot. The case should be grounded. The relay can be on either side of the load for hot switch voltages that are lower than the coil.

Why do u need a relay for LED lights?

Relays can be used to switch a low-current trigger to high current, switch a circuit on or off, reverse polarity, and much more. When adding LED lights, such as off-road light bars, driving/work lights, or other auxiliary lights to a vehicle, you must add a circuit to power the light adequately.

What is the yellow wire for on fog lights?

The yellow wire is a separate hook up to power the blue halo around the fog light. It can be connected to the running lights, ACC, etc. The fog light itself should work by plugging it into the existing plug.

How many amps do LED pods use?

To be on the safe side allow 20-25% margin so in this case the wire running from the switch should be able to handle 7.5 amps (6 amps x 1.25 for safety margin). Once the wires branch to off each individual light then that wiring should be able to handle roughly 2 amps for the 18 watt lights youre installing.

What fuse to use for fog lights?

Splice a red wire from the headlight wire to the relay terminal “30.” This line needs a 10-amp inline fuse, so be sure and wire one in. The final terminal on the relay is numbered “87.” This terminal will carry power to the fog lights.

How many amps do fog lights draw?

If the OEM fog lights draw 55 watts each (110 watts total) then the current draw for those will be 110W/12V = 9.16 amps. The formula is Current (amps) = Power (watts) / Voltage (volts). The fuse on the fog lights is rated at 15 amps.

What is a fog light relay?

The fog light relay is the electrical relay that is responsible for controlling power to the fog lights. The fog lights are lights underneath the headlights that are designed to improve visibility in dense fog or rain conditions. They are meant to help the driver see the edges of the road when visibility is low.

Which is the ground on a relay?

The second pin, or ground is the housing which must be mounted direct to chassis or otherwise grounded. If your relay is in a plastic housing it will have 2 pins for the coil, usually reversible. Your toggle switch is breaking the 12v power line between one side of coil and power.

Can you put a relay in backwards?

Relays cant be inserted backwards. The ones you can put in two ways, will work either way.

When would you use a 12V relay?

12V DC relay switches are the best solution for full voltage applications, as they allow a low current flow circuit to control a high current flow circuit, like a vehicles horn, headlights, auxiliary lamps, fan motors, blower motors and countless pieces of equipment existing on vehicles today.

What is the white wire on fog lights?

The white wire leads from the other terminal on the switch to the fogs, and the black is ground from the fogs. * If the kit has a relay: It can vary, but usually the white wire will still be the lead from the relay to the lights.

How do you test a fog light wire?

How many amps does a 100 watt LED light bulb use?

A 100 Watts bulb draws 0.90 Amps.

How many LEDS can be on a 20 amp circuit?

Technically, you can install 13 outlets or lights on a 20-amp CB, but you can only put ten lights per circuit due to the 80% rule of maximum continuous load.
