Hey guys, so I love RGB lighting and I recently purchased a few kits from Amazon; a 4pc LED strip kit for underdash/footwell(installed) and another kit for accents which consists of fiberoptics and tubing you fit into the creases of your interior (not installed yet). Also got some Hyundai welcome door lights with interchangeable films and a custom red alien head and a custom N performance logo film (below) on the way.

I installed the LED footwell strips and currently have them powered through the DC 12v, and the wire magically disappearing behind the panel to the upper left (picture below). The LED strips came with a few options to plug into a power source such as the DC 12v cigarette lighter port, and also 3 different adapters for a fuse tap option (all of which were the wrong sizes; I bought a micro2 fuse-tap separately)

I cannot for the life of me figure out how to get the fuse tap to work; I've looked up Youtube videos, I've tested the fuse-tap from both fuse boxes, using 10-20amp slots, and made sure to turn on the ignition and make sure power was running through the vehicle. I have NOT tried wiring directly to the blade of an inserted fuse.

I'm wondering if maybe the fuse-taps just don't fit in the fuse slots all the way down, causing the circuit to not be completed, but they look like an exact fit when comparing to the micro2 fuse.

My goal is to not go with the ugly, 2 socket DC 12v splitter (cigarette lighter insert) to use for both kits, and instead, utilize power from the fuse tap or from the battery somehow.


Any suggestions?

TIA

The fuse slots you tried may not be terminated.
I don't have any good information at this time, but this is something I'm interested in doing.

I used a fuse tap for a dashcam in a previous vehicle with no issues.

Thanks, finally found my amp meter, i'll go see if I can find any good fuses slots.

*Update* to **** with that fiber optic kit; couldn't get any of the fuses to power the box. Something was wrong with the power box because the fuse taps had current going out.

Even after using the DC12v to power the box, the LEDs were not strong enough to run through the fiber optic/tubing..

So i just carefully mounted the fiber optics to point into one of the LED lights on the strips I already installed under the footwells.

I bought an LED kit on amazong not to long ago. Where did you mount the strips under the drivers and passenger fronts? I took a quick look and there doesnt seem to be a flat spot to really mount to, especially under the drivers side.

The official Hyundai Accessories website has the interior lighting kit installation guide. Looks like they recommend tapping into the dimmer switch harness. I would probably trust and follow this wiring more than some random webpage or YouTube installation video.

I'm not sure that the dimmer switch loses power when the car is off and the doors opened (like windows, radio, etc.) I'm wiring in some footwell lighting today and I intend to use this wiring diagram just with my own lights. The dimmer switch was powered though when I turned the car off and opened the door. Obviously this wouldn't be good if you forget to turn the lights off and come back to a dead battery.

I'll update after the install but a microII fuse tap may be required.

So I had a chance to actually purchase this OEM lighting kit and do the install few weeks ago. The dimmer switch method only powers the lights if your headlights are also on. If you unlock the car and your headlights turn on, the footwell lighting will also turn on, acting sort of like a welcome light of your ceiling lamps. As long as you leave the headlight setting on Auto and the car shuts off the headlights after you lock the car, the footwell lighting will also turn off.

I uploaded a reel that demonstrates how the wiring works in conjunction with the headlight settings that you can watch here.

It most definitely is required. If you look at the Hyundai diagram, you're supposed to install a 2A fuse on the positive tap (the dark blue/red wire). The wiring harness on the OEM kit comes with the fuse holder but if you're using an aftermarket kit, you should definitely add a fuse in addition to making sure the wiring harness is using the same wire gauge as the dimmer wires.

Sorry for the delay but I got the LED lights installed without a hitch. I ended up using the fuse tap instead of tapping power off the dimmer switch. The lights had an inline fuse in them already but the fuse tap was the easiest way to get power, the fuse tap and inline fuse are both 5 amp. The dimmer switch wires were very thin gauge (20?) and the lighting kit I had was 16.

I ended up tapping power and tying it into a Bluetooth control box that I mounted under the center console. I used the OEM Veloster N lights install instructions as a reference for how to remove panels and ended up mounting a latching push button switch in the same location they recommended. The install took a couple hours and the lights are able to change color using an app on my phone but I have them set to a color I want and really don't plan on changing them often.

All in all I ended up needing:
  • Lighting kit (almost anything you want can be installed if you know basic electrical skills)
  • Butt connectors 16-18 gauge
  • Zip ties
  • Step drill bit for making a clean mounting hole for the switch
  • Latching push button switch
  • Some extra 16 gauge wire
  • MicroII fuse tap (comes with extra fuses so you shouldn't need to buy any to use the tap)

I can post some pictures of the install if anyone wants but it really was simple, especially with Hyundai's OEM install kit as a guide (below).
