I had a 2nd generation Ram, it was a simple mod to leave Fog Lights on when switching to Hig Beam, bending a relay pin.

3rd gen looks like different.

I tried your mod to keep Fog Lights on, but they are always on and internal switch control is lost, just always on.


when switching to high beams, flog lite relay goes off.

it looks like high beams don't have a relay, I can't hear any "click".

so, target is have the fog relay on whith high beams only and still have internal switch controlon: any clues?

thanks[/align]

 

Yes, it's easy. Go to the top of the page and click in the icon that says SEARCH.

 

hey man, It's simple: read my post before... looks like I already tried that mod...

 

i have a hard time following this.... what i did was use the jumper wire between my running lights and fog lights and my fog lights are always on and that includes when my high beams are on....

 

Here is the simplist way I can tell you to do it. Take out your fog light switch and get a wiring harness or test light and figure out which wire it gets power (12 volts) from. Then find a source of 12 volts when the ignition is on (radio, lighter,accessorie, ect...) and run a jumper wire to the switch so that it has power when the swtich is on. I did this on my 95 way back in the day so I could have the driving lamps on when I had the high beams on. I wired mine to my parking lamps so that unless they were on they would not come on, however yu can wire it to any source if you like and make them so thay come on regardless as long as you hit the button. If you still need more help drop me a personal e-mail and I will get you my phone number and I will get a wiring schematic for your truck Mondy night when I work again and we will run through it together over the phone...

 

thanks Vader, appreciate that!

well, I was reading the schematics, looks like fog lights are triggered by negative...

I was going to pull that switch out anyway :-)

another mod could be tapping a wire to high beams to power a relay and send a negative signal to fog relay. (relay is necessary to invert positive trigger from highs to negative )
