Default Wiring help needed

On a trip to the treasure(junk) yard, I picked up a fog light button and the plug part that plugs into it out of a '98 Outback and need to hook it up to my Hella's which the current switch for it has two wires (power & ground). The OB button has 6 wires coming out of the plug end.
Now, the fun part where I need the help is what wires do I connect to get the Fog button to light up like the CC and Defrost buttons (Green-off/Orange-on) and also turn On my hella's? Easy instructions for the electrically challanged would be great Tried looking at my Hayes manuel and it doesn't really tell "me" much.

Mark,

If the button is a push type button....similar to the cruise and such....like they are on the first gen legacies. I can tell ya what is what, and what you'll need.

Take a looksie at this pic


Ok........had a major brain pondering when I was almost done. I looked at some more info from the FSM's.....and I think I got everything figured out now.


From what I can tell. 2 & 4 are simply hookup of power for the back lighting in the switch. You would want to tap into a pos power lead going to another switch or another spot that has power for lights. Then you would tie the other to a ground.

So, for ex. You'd tap into the power lead on the switch next by. Run that to 2. Then you'd run 4 to a ground.

If the switch is setup the same, you should then have lights when you turn on the interior dash lights, and it should also dim with the dimmer.

3 & 5 and 1 & 6 are tied into the pressing of the switch. Here's where I'm not 100% sure, without actually having the switch in my paws and testing the leads. Either 3 & 5 control the actual on and off that goes to the relay to turn on the fogs. Or 1 & 6 does it. The pair that does not actually go to the relay turns on the orange light or whatever color it is in the switch to let you know the fogs are on.

I am pretty sure, 1 would be a 12v pos. 6 would be ground. I'm thinking that when depressing the switch it will turn on the orange light.

What I would suggest doing is taking a ohm meter, set it to continuity setting. Double check what I have said. 2 & 4 should have continuity all the time, regardless of switch being on or off.

1 & 6 and 3 & 5 should have continuity only when switch is depressed. Technically 1, 3, 5, and 6 should all continuity when switch is depressed.....

Ok.......I know this is sorta jumping around......I hope it makes sense. It would really help if I had the switch in front of me, and could do some probing around.

If you want to get this thing working......I'll work with ya and we can try a couple things to make sure it's setup correctly.

Josh

i did this for my hella driving lights... snipped the switch and wires out of an OB Wagon.... got the switch to work, red light on switch comes on w/ lights on, but backlight/dimmer doesn't...

I used diagrams from impreza fog switches... i'd have to yank my switch to confirm which wires went where.

Sorry I'm no help right now... went I get to tinkering, I'll take some picks and confirm what's what, and hope to get the illumination-dimming correct.

Good luck

Thanks for putting in the helping hand, Josh. The switch is exactly what you'd find in any 95-99 OB. The plug part looks just like that bottom right diagram in your picture with wires 1-6. I want to wire it up right so I'm not running into what "snowone" ran into

As you see by my lovely work of art I already have a power and ground coming off the battery. And taking a guess here, would 1,2,3 be wired into the power lead and 4,5,6 to my ground?
Set me straight

Well, at least one of those pins has to be an output for the switch to do anything.

Rather than from the battery, I powered my switch with a tap off the fuse for the dash illumination. That way, the fogs only come on when there's some type of lighting on (park, low, hi beams). Also the backlighting comes on when the headlights are on... the only cavaet is that the backlighting doesn't dim with the rest of the dash lights, but that doesn't bother me...

Anyway, I'll see if I can dig up a diagram for the switch in a 95-99

Here's the page on the wiring diagram. It's big so I'll just post the link.

Mine isn't set up like that, and if I have time I'll try to figure out what I did.

Ok, so essentially what I did was tie pins 1 and 2 together and tapped into the dash illumination fuse. Then you get the results I mentioned above.

Thanks Guys. Friday is looking good for some personal time between me and the car so I'll let you know how it goes with this switch and me.
