Cn 6224 Schematic For Connecting Fog Lights To The High
How to wire fog lights to high beams. Turn on the high beam headlamps. The fog lights each have two wires one for ground and one for the 12v power. The easy way to make this work. Put a diode between the high beam power wire and the fog light power wire. Connect the end of the circuit tester to ground and use the tester to locate the headlamp high beam lead. Leave at least one foot of wire hanging after the tape to leave enough slack for the connection to the lights.
Use the following procedure. A three way connection must be made joining the second wire from each of the fog lights to the red wire going to the relay terminal 87. One of these wires from each fog light has already been connected to ground. Turn on the low beam headlamps. Turn off the ignition and the headlamps. When the coil of the relay is energized 12v from the high beam switch to terminal 86 ground on terminal 85 the normally closed contacts open interrupting 12v to the fog lights.
Terminal 87 is not used. The power supply wire will run from the high beam relay wiring harness to the driving or fog lights. Low beam operation is unaffected so you can turn your fog lights on and off and never lose control of your fog light switch when not using high beams. Wiring light bars to your high beams duration. Route the power supply wire. So that the power from hi beam will send power to fog lamps but the power from fog lamps will not back feed to the high beams.
Connect the end of the circuit tester to ground and use the tester to locate the headlamp low beam lead. Wiring hid low beams and fog lights in my 04 tahoe and auto fog lights duration. Start by taping one end of the power wire to the metal bumper support. Power 12v to the fogs lights passes through the normally closed contacts of the relay terminals 30 and 87a.
