Who out there has the PILP (option 317) Premium Interior Lighting Package?
The key issue (for me) is that it includes "puddle lights", which are on the bottom of the front doors, illuminating downward to help you enter and exit the vehicle, seeing what's around the car.
Thing is, I "remembered" that my GLK had that option until I went to remove one of the "door lights" and came up with just a thin red plastic lens / reflector for my trouble. Oh, yeah... NOW I remember... that was my BMW 530xi. Oops.
I ordered a , that include a tiny little projector that projects the MB "ear of wheat with tristar" on the ground below each door (when open), which is a cool option. Thing is, I'm not really willing to run power into my door to install the things (yes, there's no plug for the puddle lights if your GLK was built without option 317). Note that the listing for the lights don't show the actual "ear of wheat" but only a circle, which is (I'm finding) common for those selling parts with MB logos, but not OEM suppliers.
Thing is, I got the projectors / lights as part of a program where I review items that are provided, and can't do it (properly) with my vehicle (or my 2012 "project GLK", which is also puddle-light-less").
If anyone out there DOES have the option 317 and would like to install a pair of these projectors (which should take literally 10-20 seconds a side), I'd be willing to send them to you, in exchange for just letting me know how the install went and a quick photo of the projection. Basically, if your car has puddle lights, you're good to go.
Anyone interested?

I hope someone can make use of these puddle light projectors, and would love to see how well they work. I promise I'll only be a little jealous. ;-)

Because the door cards are riveted on there is no way I would want to mess with them. If they were simply screwed on sure.
Mmr1, the wiring you're looking for is actually not in the door, but in the switch controlled by the door opening and closing, and that's mounted in the body's door frame. In an old-school car, it was a pin-button switch sticking out near one of the door hinges (from the body, not the door), hooked up to 12 volts, with the switched side going to the dome light circuit. I'd bet that the GLK has a little more techy way to do it, running it through a "something-BUS" circuit. I suppose it's always possible that there IS a connection to the right wiring already somewhere inside the guts of the door, but I'll bet it requires reprogramming to make it work.

Not that important but on the older cars I worked on, that had the push-in door switch, they always supplied/connected Ground when the door was opened (as opposed to supplying 12vdc).
If it's an incentive, the manufacturer included a video showing the projection, and I'm impressed - it looks really good, though the screen shot I captured shows someone holding it at an angle, resulting in a slightly distorted circular logo (looks like it projects a true circle on the ground once installed)...
I really do hope someone asks for these (in exchange for letting me know how they work out so I can do my promised review). Otherwise I may be tempted to start hacking into my wiring harness and cobbling together a DIY install for puddle lights. ;-)

I wanted the interior lighting package, puddle lights etc. when I put in my order and I thought the price of $300.00 was okay/reasonable. Then I was told they could no longer order a 2013. It had be a 2014 and I agreed but the "clowns" dropped that lighting package and I missed it in the new build sheet. In any event, I later wanted to install the footwell lights and puddle lights but didn't get around to it. I did try to find those damn puddle lights with NO logo but could not. I want even light on the ground and not advertising. And, frankly, I find the logo lights in the same category as a lighted Mercedes star on the grille. Not my cup of tea... still, I would take the advertising puddle lights over none but only if I knew there was a constant 12 volts somewhere in the doors (minimal work). It appears there is not :-(
Your offer is appreciated, though.

Funny thing happened when I was cleaning up the (filthy) GLK - I bumped the triangular panel on the front of the driver's door, and it fell off, revealing the door control module. Who knew it was where you can (theoretically) get to it without pulling the whole door card?
Anyway, that led me to a fresh round of research (hoping to come up with an easy solution for others to install puddle lights, and create a video to share it), and think I might have it on the run. I ran down a schematic for the door control module, and saw that the puddle light (driver's side anyway) was designated as E17/3. That plugs into the DCM in plug #6, and connects to pins 3 and 4 (currently empty, of course). I tried (in vain) to find specs for the connector pins to populate the existing plug #6 body, or for connecting to the puddle lights (I was just going to use generic crimp-on pins if necessary). But finally I tripped over a supplier of pre-wired "wiring harnesses" for the GLK front door puddle lights, with the (hopefully) correct pins on the DCM end, and an honest-to-gosh plug that should plug into my puddle lights (assuming THEY are actually MB-spec, of course). Even better, the cable is covered with that felt-like tubing that keeps the wire from rattling around, which is important because my plan is to install the harness by loosening only the lower and front edges of door card. Should be more than enough.
If it all works out, I should be able to make the upgrade and post a video on the process, showing how to install puddle lights / projectors for well under $50 and (hopefully) an hour or so total time. The one potential stinky wrinkle is if the DCM needs to be programmed, it won't be a real DIY job for most folks (who might not have bidirectional MB-enabled scan tools). I'm hoping it'll work as-is, and if it doesn't I do have a fall-back plan (hack the pins off the harness and connect them to two other points in the DCM harness - a full-time hot lead, and a switched ground that's grounded any time the door is open).




Should be a fun project - as long as I can a) wiggle the DCM loose enough to get "testing access" to the pins for plug #6, and b) it doesn't require reprogramming of the DCM (which I can probably do, but which will seriously limit the number of folks who might benefit from the info I'll assemble).
I finally got the pre-made wiring harnesses, from a really accommodating eBay vendor. The first shipment was mis-delivered, and they replaced it free, and were very helpful with advice and technical data, all for a sub-$20 purchase.
The harness allowed me to add pins to one of the plugs in the driver's side DCM (Door Control Module), and to connect directly to the pins of the DCM on the passenger's side. However, for some unknown reason, I wasn't able to get power from the DCM to get the lights to work.
So I fell back to a "hacker option", cutting off the female pins from the DCM end of the harness, and wiring the wires to a full-time hot wire, and to a switched ground that's grounded when the door is open. Worked like a champ. Doing it correctly (pulling the wires out of their respective plug housings, soldering and applying heat shrink) took some extra time, but I wanted to show the right way. I'm sure that a much quicker slice, solder and tape method would be adequate given the protected area the cables all live in.
At any rate, the video will be available shortly, and shows the install process, as well as both wiring options. I'm really pleased with the (very!) aftermarket projector puddle lights - the MB logo they project is very sharp and appropriately bright.
It was all much, much more time and trouble than it's worth, other than because of the opportunity to learn something, and to help others figure out how to do it without spending so much time researching and flailing. ;-)
