Default RE: How To Keep Your Fogs On While High Beams Are On

I just intslled myOEM fogs this weekend and I couldn't be happier with them! I still need to adjust them a little, but they were worth every penny! From the directions that came with my kit, the last step was to take it to the dealership to have them StarScan it to have the fogs turn off with the high beams. Needless to say I won't be doing that. I guess that's where the difference is on the '06s, the fogs are supposed to be computer controlled. Next onthe mod list: 3" front springs leveling kit.

Default RE: How To Keep Your Fogs On While High Beams Are On

So for my 01 dakota, I just pull the fog lamp relay and short out the 2 terminals that face opposite the other 3? Does this only accomplish making the fog's stay on with the high beams, or does it make them come on anytime the running lights are on? I want to be able to use the pull/push function to kill/activate the fog lights wether i'm in running, low, or high beam, since i use the fogs to flash people, i want to be able to flash them regardless of what the headlights are doing.

Hmmmm... Why does this conjure up visions of burnt out ruined wiring harnesses in my mind? [sm=badidea.gif] I wouldn't do it.
It may if you don't understand what's being done. The wires being delt with here are low current, meaning less than 1 amp travels through the jumper wire. The fog relay is being powered, not the fog lights. There's a big difference in danger there. All the current for the fogs still travels through the stock circuitry.

Here's an even better question for me to ask-

Where is the circuit that ungrounds the fog lamp relay when the brights are activated? Can't you just cut the spade off the relay that does that? So that it no longer ungrounds it? And same thing for the low beams? That way you can have fogs, low's, and high's all on at the same time (and kill the alternator)?

To answer your first question, you lose all control over the fogs when you do this mod. They're on any time the parking lights are. Not ideal for me either so I haven't done it yet.

For the second, in a short answer, no you can't do that. These trucks no longer use simple mechanical switches to control the lights. A signal is sent from the light switch to the body computer which then triggers the appropriate lights. That computer decides "fogs have been requested but the high beams are on so I'm de-activating the fog circuit" and that's that. Removing that control also completely disables the stock fog switch.

The only way to do it the way you (and the rest of us) would like is a separate fog switch plumbed into that pin of the stock relay. Well, that or a reprogram but apparently no dealer is willing to do it. I haven't asked here yet.

why can't vehicle electrical systems be like they used to where you can just change relay sockets and number to make anything do whatever you want? lol

That, or somebody that works at a dealer needs to get a prgrammer and take it to TI to have them duplicate it as a mass production unit so everybody can reprogram anything in the computer.


afterthought- who says we can't rewire the light switch on the dash to do what we want and bypass the computer all together? So fog control goes straight to an external fog relay goes straight to fog lights, low beams go to external low beam relay which goes straight to low beam connectors, and high beams stay on the column and stock (and parking circuit stays stock)? Then leave all the stock wires as-are so the hack can be undone and/or the computer won't lose it's mind. That'd give you full control over the lighting with exception of turning low beams off when high's are on (for potential legal reasons).

That's how I've done it on every other vehicle I've ever owned. However, as I understand it, the stock headlight switch has only 1 or 2 wires that tell the computer what choice or combination of choices you've selected with the ****. The computer then activates the desired lights.

The actual switch isn't connected directly to the relay anymore.
