so I purchased some switchbacks for my front turn signals and got home and followed what little info is in the owners manual to change out the bulbs, we'll it was really hard to even access to bulb through the fender liner, and when I finally did get the bulb out an hour later there wasn't enough slack for me to even work on the wires to put in the load resistor, do I remove the bumper or what, is there any DIY on this job or any info please, you tube videos?
