99 Fog Light wiring diagram or pin outs or something
Trying to wire up a light bar to the factory fog light switch. The car didn't come with fog lights so I have no relay under the hood only a dummy dust plug cap over three wires. Those three wires I have no idea what they go to. I know the center one drops to 1V from around 12 with the fog switch pushed in but the others stay around 12. Are they grabbing the coil high from the relay to one of the 12's then switching ground or what? Is one of them powerful enough to support the ~10amp draw?
Can anyone tell me how the factory relay harness is wired up or find a schematic.. none of the 4 schematics I've found show fog light circuitry. |

Every dumb tutorial on the other forums assume you have a relay or had foglights and mine just has a switchhttps://cimg2.ibsrv.net/gimg/www.mia...517652f382.jpg |
Add in a standard relay.
Red/Green to one side of the switch in the relay (30) Power to the light bar on the other side of the switch in the relay. (87) Red/Yellow to one side of the coil (85) Pink/Blue to the other side of the coil (86) Ground the light bar. |

thanks So much for my 15 buck wiring harness lol Confirms what I was thinking |

not proud of the wiring job I did but it works and should be waterproof somewhat. Thanks loads for the advice |
