Are both fog lamps hooked to one wiring harness?

 

Yep, the bulbs are only like 12 watts.... or something stupid like that.

 

I have one identical to the horn plug. I always figured it was for the dual-tone horns since I just have 1.

 

If you have two bolt holes right above the light housing hole, you should be able to install factory fogs.
Yes: they are pigtailed.
uh hem..being someone who just replaced their bulbs, I can say with out a doubt that they are exactly 37.5 watts.

I looked under my truck last night and didn't see the plug where it would have been, however, I DO have fogs on mine, so it likely isn't in the same place as a truck that didn't have foglights.
BTW, lol ->

 

Ya if it might be that Dodge put those there to allow fog lights to be added later. Tonight I might have my dad hold a volt meter in that plug and I'll turn on the headlights. Hope fully there will be a reading because there isn't a button on my dash to control it.

 

I had dual tone horns and there is only one plug on it.

 

Should be a relay in the PDC for fog lamps. (or, in your case, probably a socket, with no relay.....) Fog lamp switch just controls the relay. Headlight switch won't do anything. (aside from kill them when the high beams are switched on.)

 

Interesting. Maybe its for the fogs...

 

Ya I never got around to check the voltage on the plug but I am going to look around for anything that even looks like a relay under the hood or in the fuse box.

 

Will be in the PDC under the hood. Should be a legend on the underside of the cover.
