I've been sick of the plastic shrouds where my Tig's fog lights should be, so I capitalized on the ECS Fog light conversion sale and just got around to installing them today.
I followed these instructions for a MKIV Jetta after removing the bumper. The instructions were pretty much the same for the Tiguan, however the first few steps were not necessary. The worst part was fishing the trigger wire through the firewall wiring harness boot and up into the dash to my euro switch; HUGE PITA!. A coat hanger is essential! The rest of the wiring harness from ECS was easy to understand and install based on the Jetta instructions. I chose different grounds because the Tig doesn't have the same ones as the Jetta.
It took me about 3 hours being careful and taking my time to do it right. I'm very happy with the ZiZa Platinum White bulbs that I swapped into the housings to match my headlights. The front end looks complete and I love the look with my LED city lights accompanying them!
Light cannons FTW!!
Next up is the Hella Blackout headlight housings, but I'll wait on a sale. $500 is a lot for just housings!
