I just did this mod to my SX 5. I used a relay triggered by the marker lights to turn the fog lights on with out the headlights. Any time my marker lights are on my fog lights are on, no headlights required. I like the look of just the fogs and the marker lights.I'm new to the forums. This is my first post. I haven't seen an answer to wiring the fogs so that they can be enabled with the parking lamps. This is what I want to accomplish. I don't want them wired so they're constantly on, just wired so that when the parking lamps are on, and the fog lamp switch is on, the fogs will be on with the amber lamps. Hope to hear from someone on this.
All you need is a wired relay. I used the marker light positive wire off the headlight module plug to activate the relay. It's a green wire with a pinkish/orange stripe. One side of the coil on the relay gets the marker light wire. One side of the open contacts on the relay and the other side of the coil on the relay goes to ground. The remaining open contact on the relay goes to the trigger side of the factory fog light relay. The picture in the first post of this thread shows you that contact in the relay socket. Mine's a 2012 and the factory relay is controlled by the BCM, so one side of the coil on the factory relay is always hot. Simple matter of supplying ground using the relay which is triggered by the marker light positive wire. I unplugged the factory relay and inserted a short length of twisted wire from the output of the relay in to the receptacle then I plugged the factory fog light relay back in along with the wire.I'm not good with wiring, can you provide pics or explain more on how you achieved this? I've been waiting for someone to figure out how to turn on the fogs only with the corner lights.
You still use the original fog light relay.
Yep. The part where you can't turn on your fogs using the switch unless the headlights are also on.maybe i am misunderstanding something here and if so please forgive me. Since the fog lights have a separate switch, i just leave them on all the time thereby i have DRL's. Am i missing something or is this mod not needed?
