Aftermarket Fog Light Switch ???

Ok, here's the short version.

Hella 500 Series Driving Lights
Basically have all the wires ran
Still need to ground fogs
Connect Power to fogs
Hook up Switch

I have the relay hooked up as shown in the diagram. Here is my question though. For the switch, I've got the yellow wire coming from the relay, and the instructions say to tie the other (green) wire into the high beam power source. I want these lights to operate completely independant of the high/low beam system. What do I do with this green wire??? Obviously, it needs some type of power coming to it, correct??? I assume that I can't simply run it back to the + terminal on the battery though, can I??

Thanks.

That wire is the positive to the relay. Either hook it to an ign source (only on with ign. on to prevent accidentally draining your battery.) If you want it to come on with parking lights hook it up to the parking light wire, ect.. You can run that wire to the + of the battery but you will have to manually turn off the fog lights at the switch every time you shut off the truck.
Thanks for the quick answer.

Any idea which wire is the parking light wire? Hard to get to??? I assume that I can trace it down from the stalk somewhere??

Correct me if I'm wrong:

IF Fog light switch is ON AND Parking Light switch is ON, the fogs will turn on.

IFFog light switch is OFF AND Parking Light switch is ON, the lights will be OFF.

IFFog light switch os ON AND Parking LIght switch is OFF, the lights will be OFF.

Regardless of how it is, the Parking Lights would need to be ON for them to come on as well, correct?

Thanks for all the help you provide to everyone baseballfanz, not just to me, but everyone else on this site and others. I can't tell you how much we all appreciate your knowledge!!:cheers:

Ok, So I tapped into the + Parking Light wire and have power coming back to the switch. I'm unsure about the switch though, no matter which way I configure the wiring on the back of it.

There are 3 terminals on the back of the switch:

1 for the green wire pulling power from the Parking Lamps

1 for the yellow wire going to the relay

1 for ????

Do I have to ground the switch? How do I hook up the switch???


Thanks again.

OK, so I successfully blew the fuse for the Parking Lights, can't seem to locate where it's at now though. What a PITA!!!
The fuse is either under the hood or in the fuse panel by the glove box (passenger side).

The switch has 3 wires, one goes to the relay, another get grounded, the third goes to a 12v+ source for the little light inside the switch, when the switch is on it light up.
Check out the picture. I show how the diagram on the back of the switch looks:

Earth SHOULD be the ground

Load SHOULD be to the relay

Supply SHOULD be from the parking lights

Correct???


When I hooked it up that way, I lost all power to the side marker lamps, turn signals still work, headlights still work. Hazards still work

I've checked every fuse that seems like it would be related to the side marker lamps, they are all ok.

I just hooked mine up last Sat. with the same kinda switch and came right off the battery for power...
Didn`t want to mess with any of the fuses or wires in the truck...Mine is working great..
If i accidentally leave the fogs on, it will teach me a lesson next time !!!!
I would only be using them in dark or foggy situations and the illuminated switch will help me out if i leave them on....Plus they are some bright mofos !!!!!
Good luck.......
Well, after taking a short break from it, and regrouping. I was able to confirm that my ground for the lights themselves was no good. I still haven't been able to locate the blown fuse for the "Side Marker Lamps". All the other lights still work, I'm basically stuck at this point until I can locate that fuse and someone can tell me how this [email protected] switch is supposed to be wired.

Thanks,

From what I recall, the Green from the switch goes to the High Beam (in this case you hook it to the parking light)
The Yellow goes back to the relay post 86
The Blue is grounded.

Thanks, I'm pretty much stuck until I figure out wha't sup with these Side Marker Lamps now. They don't come on, which means I don't have power to the switch.

Note that the truck still "thinks" that the lights are on though. It beeps when the parking light swtich is turned on and the drivers door is opened. All guages work and everything else electronically seems to be fine.
Problem Fixed. Lights are hooked up and working properly.

LESSON LEARNED: Make sure the system is grounded properly before rushing /making bad decisions. Had I done that, It would have taken me about 1/2 the time and 90% of the aggravation.


Again, thanks for the help in this matter.
