Is this possible?

[00XLS]

I'd like to wire up my fogs and backup lights to come on with my interior lights, like when I use the keyfob to open the door locks. I think this would be a cool mod to do. I think it would be fairly simple, a relay and running some wire from the circuit of the interior lights NOT THE MAP LIGHTS, to the fogs and back up lamps.

Anyone? I realize anytime that I have the interior lights on my fogs&backup lights will be on as well but is there away to wire around that? I have the factory CD so I just need a lil help here from the wiring experts.

what about when you are driving down the road and need the interior light? your reverse lights will come on?

This would be simple to wire, you just need a power supply and relay withthe interior lights being the trigger wire for the relay, not that complicated, just a PITA.

this could be pretty easy

you could use the door switch on the inside of the door panel... but why would you want the exterior lights come on with the interior? i guess you got your reasons haha..

but it might only work when you open the particular door you wire it too... i would have to see a wiring diagram of that system to tell ya where to put it.

Its kinda like the puddle lamps, they come on with the doors being unlocked. Similar thing here, I know the new *gulp* GM cars have their daytimes running lights and reverse lights come on when you unlock the doors via the key fob. I'd like to have that in my truck as well.

The easiest way would be to wire a relay to the lighting circuit so when the lighting circuit is energized, the relay would be triggered and light the fogs and back-ups. This would also light the fogs and back-ups if you are driving down the road and turn on all the interior lights, or if you open the doors. To avoid that problem, you'd just have to study the wire diagrams on your CD and see if there's a solution. If the keyless entry system has a trigger for the interior lights that is separate from the door and headlight switch triggers, then you could wire a relay into that trigger followed by a diode, then the fogs and back-ups would come on only when you use the fob.

My guess is that a factory-installed system will have one central module that receives inputs from door switches, the headlight switch and the keyfob and has only one output to trigger the interior lights, so my solution would not be possible. Then you'd have to do some more complicated wiring with relays connected to the door switch and headlight switch circuits that would interrupt the power to the fog/back-up light relay if the interior lighting was energized through those means.

It's hard to explain this without drawing a picture. Hope this helps.

I'm understanding what your saying for the most part. I'll have to look at the wiring diagram and see whats what. If you have time a picture would be appreciated as well. Everything seems simple enough until I want to have interior lights with no outside lights but maybe I'll get lucky?
