Electrical question for hyundaitech
hyundaitech, I don't know if you can help me with this question but here goes. I'v got a 2003 GLS with sunroof. Unfortunately, the map light switche aren't illuminated and I'm tired of driving at night and fumblin around trying to find the map light switches, only to hit one of th the roof switches by accident and have the roof retract on me. Havin that happen is especially frustrating when it's raining out. To solv that problem I want to install two very small 12 volt LED's into th sunroof control panel to mark the position of each of the map ligh switches. Physically installing them into the panel won't be a problem My problem is trying to figure out where I can tap into the contro panel itself to get a switched 12 volt positive feed for the LED's. bought a spare sunroof control panel to play around with and I've fe 12 volts into it and I've noted what each of the connections are for For obvious reasons, I'd like to try and tap into the power connection in the sunroof control panel or headliner and avoid running power lead to junctions elsewhere in the car. I've got the Elantra electrica manual, but after looking at that for a while everything starts gettin blurry. I'd love to be able to power the LED's on when I turn on th parking lights or headlights but I guess I'd be happy if I can ge power to the LED's when I turn the ignition switch on. I really don' want to have the power feed be hot all the time for obvious reasons One thing that I may be able to tap into is the spare roof lamp harnes that's up in the headliner. I saw that unused harness when I wa installing the one-touch sunroof control relay some time ago but I kno that room lamp is controlled by the ETACM. Any suggestions that you ca pass along will be greatly appreciated. I don't suppose Hyunda redesigned that panel to incorporate lighting for the map ligh switches?

Re: Electrical question for hyundaitech
Probably the easiest/nearest place to tap in would be the brown/black wire
going to the sunroof relay. This wire has switched power. According to the schematics, the only wires power wires going to the lamp/sunroof control assembly either have constant power. The brown/black wire goes through the relay coil side before getting to the lamp/sunroof control panel. If you want to use the tail lamp circuit, the rheostat (dimmer switch) is a good place to tap in. Wire the positive LED lead to the black wire at the rheostat. Then wire the negative to the green wire if you'd like the LED to dim with the rheostat, or simply attach to ground if you want full LED illumination anytime the tail lamps are on. The wiring to the roof panel runs up the left front pillar. The trim should simply snap off. It's probably not a terribly involved project if you wanted to actually tap into the dimmer. |
Re: Electrical question for hyundaitech
There's a simpler solution; install a tactile indicator of some sort on
each button. It can be something as simple an unobtrusive as one of the small rubber buttons used on computers, furniture and the like. You can get them at any hardware store or home center in a variety of shapes, sizes and colors. |

I think that' the (very simple) answer that I've been looking for. Thank you fo pointing that out. I was so focused on taping into the control pane lighting circuitry that I forgot all about the relay circuitry. I looks like pin 2 on connector M96 will do it. No doubt that would wor with the stock relay, but I'll have to see if that will also work wit the one-touch relay that I installed. I also appreciate the othe suggestion about tapping into the rheostat. It sounds easy enough eve with having to remove the trim panel. Having the LED's tied int illumination control would be even sweeter and I may end up going tha route eventually. For now, just getting illuminated indicators overhea would be a tremendous improvement over total darkness. Thank you! You did such a great job with that question, I'm wondering if I ca bother you with one more electrical question about the Elantra. I nee to install a dash switch to control my GLS fog lights so I can tur them on and off as needed. The power and ground connections for th switch in the cabin will be pretty straightforward, but somehow I nee to get a powered lead (connected to the new switch) from the cabin through the firewall, and then into the engine compartment. Just on wire would do it for me. I've looked just about everywhere for simple, easy access point or plug, but short of drilling a hole throug the firewall I can't see a very direct route, although I may hav overlooked an access point somewhere. I was hoping that one of th harnesses going through the firewall would have an unused lead and just could hitch a free ride on that. But from what I can see, i doesn't look like Hyundai has any unused leads in the harnesses. I your vast experience, do you know of or have a fairly simple suggestio for getting a single wire connection from the cabin and into the engin compartment by going through the firewall or otherwise on an '03 GLS? don't mind doing a little work to make it happen as long as it doesn' involve tearing the entire dash out or pulling a fender off the car. asked my dealer how I could do it, and I was even williing to pay the to do it, but they didn't even want to talk about that kind of "voodo magic". I'm open to suggestions.

With an LED, you go right to it. I too, often fumble for the switches. A simple feature I miss is having the dome light come on when I turn the key off. When I pull into my driveway at night, I turn the car of and I'm sitting in the dark looking for the papers on the seat, of my hat, etc. In my Buick, the light comes on as soon as I remove the key and stays on for some time after I exit. The Buick also cost thousands more and yes, you do have to drop some little features to keep the cost in line. |

I'll need to look into this tomorrow. I'm not at work and am on Mac, so I
can't view the website. |

Re: Electrical question for hyundaitech
Start by checking to see whether you already have fog lamp wiring in your
car. Are the connectors for the fog lamps themselves present? Do you have a fog lamp relay in the underhood fuse box? Is there a 15A fog lamp fuse in the underhood fuse box? Is the green/orange wire for the fog lamp switch present at pin 12 of the multifunction switch connector? If all these things are present, all you really need to do is tap into the wire at the multifunction switch connector for your own switch (or even replace the multifunction switch with one for fog lamps), find a ground for the switch, and mount the lamps and connect to the connetors/wires already in place. Even if the wire at the multifunction switch is the only thing present, that's your path from inside the vehicle to outside. I know it'll make you dizzy, but comparing the schematic to what's present on your car is an excellent place to start. Then it's a matter of engineering something simple to work with what's already there. |

Unfortunately, there's no fog light relay or relay socket in th underhood fuse box and consequently no harness wiring that I can see Nada. No fog light connectors either. Yeah, I know, that would hav been too easy. I've already checked for that. I'll have to check an see if there's anything at all at the multifunction switch becaus you're right, that would provide access through the firewall. There' no relay socket connections in the underhood fuse box so I kind o doubt there's any existing harness wiring anywhere. I was jus wondering if in your experience you knew of an easy way to do that o knew of an available access point through the firewall.
