So I've searched around TW and asked questions on other threads but they all seemed to be dead.
So I have a brand new '13 and i'm like "MOD THIS BITCH" so I start with something easy. well the foglight mod works great but now my headlights are on all the time regardless of the light setting on the steering column arm. Anyone know why?
- Is it because I did a quick splice to the red/black wire under the fog relay?
- Would this NOT have happened if I had bent the relay tab and connected to that instead?
I'd try it out but I'd like to hear from some people before I go bending my relay tab and accidentally break it off which is part of the reason I went the splice route to begin with.

Thought I'd condense the info here so people don't have to read through all the back and forth posts.
First, thanks to every who contributed. I appreciate you taking a the time out of your day to help me out.
So user tdunc had a great point which was that since the natural operation of the fogs is to go off when the low beams go off, they must be tied together via the red/black wire feeding to the Fog Relay. Thus, since I used a quick splice, I'm reverse sending power back through that red/black wire and feeding the headlights constantly. But this is just a theory...
I'm going to test this out tonight after work and will update for all to read.

IT WORKS! So I removed my quick splice and went the bent relay tab route (just so people know, the amount of insulation that is removed when using a quick splice is negligible...mine had a nick about a centimeter and was only nicked on one side of the wire; quickly patched up with a little electrical wire).
Our theory was correct. The quick splice was sending power back to the headlight relay thus forcing the headlights to be on all the time. Not sure how many models this applies to (probably any with foglights) but the quick splice route is not recommended for the anytime fog light mod.
Couple things to point out about this mod:
- be VERY careful bending the tab; make sure to bend it very slowly and no one will get hurt. More importantly, be even more careful attaching your blade connector to the relay as sometimes those blade connectors are very hard to slide on to the tab and if you apply too much force, you could cause the tab to bend back quickly which will very easily fatigue the bend point of the tab. These tabs can only handle so much bending before they snap right off. I'm sure relays are cheap but it's just a pain in the ass that I'm sure you'd rather not have to deal with.
-(only applies to 2012 and newer) When re-attaching the secondary panel cover that houses the fog relay, sometimes the blade connector will stick out at a weird angle making it tougher to put the lid on. It can be done and closed completely but you just can't try to attach the hinge points first and then close it like a clamshell as you normally would. you have to kinda put the left side in first then kinda jimmy it in place...you'll see what I mean if you're affected by this.
