Hi.. I have factory fog lights installed on my truck that didn't have em. I have them wired to a toggle. I'd like to have them wired to my headlight switch if it's not too complicated. It seems I have a connector under the radiator that I'm guessing would go to the fogs. Is this correct? And.. I would need the push/pull switch. If I got one... would it be plug and play? What's involved in swapping the switches.. do I need to dismantle the entire dash? Would I need a harness and switch specific to my year? I'm adding another set of fogs to the front and lights to the back and would like to keep toggle switches to a minimum. Thanks in advance...

Most likely your not going to like it. If you wire to the headlight switch then you going to be bound by the lo beam only mode that Dodge provides. So if you turn on hi beams the fog light go off. 

Me personally I did something way different I use the fog light signal to toggle a relay and allow to have 2 bulbs on lo beam and then 2 bulbs on high beam. This way I kept the control from the dimmer switch and headlight switch still controls the light on or off.

Thanks for the info Mike... but... can what I'm asking be done? Do I need a harness and switch specific to my year truck?

Most of it should be already there. Just need the headlight switch, fog lamp relay and the plug is typically under the radiator or near that area. 

I have a plug there but no harness to go from there to the lights.. that's why I'm asking if that harness is year specific.. 

Unknown on that part...  The only thing I can say is hit a wrecking yard for that piece. 

Yea go find one at a wrecking yard.  

If you can't find one you should be able to get the pig tails and make your own harness it's should only be 3 or 4 wires and 3 plugs.

I believe the correct connectors are on the light end of my current wiring. Just need the plug end for the connection under the radiator... I'll hit up a couple of junk yards

I am planning on going to one later today I will see what I can find 

If I did find a harness and a switch... how would I incorporate a relay? Is there a spot for it in the fuse box next to the battery? 

Exactly. There is a socket in the PDC for the fog lamp relay. 

Awesome.. I have a line on a 2001 harness... just not sure if it'll work on my 99.
