w202 facelift door courtesy lights

Some of you may know that I have been trying to find out how to fit the courtesy lights in the bottom of the front doors, as found on the elegance and other models (not sport).

Koolvin's thread:
(puddle light mods complete (BIG PICS and VIDEO))

Those instructions will only work on pre-facelift models, so were not applicable to my car, and I have been unable so far to get any information from the stealership parts guys or any other website/person. This is no longer the case! Many thanks to MikeC200 who provided me with the correct pins in the door control unit of the facelift w202 so I could wire up the courtesy lights :D

If you want to try this yourself, it's a LOT easier than with the pre-facelift models and it's also very cheap (about £10 for both sides).

You will need to buy:

A 008 545 55 26 : contact bushing : x4 (I recommend doubling this because you will mess them up or lose them, trust me ;) )
A 202 540 69 08 : cable harness : x2
A 126 820 13 01 : interior lamp : x2
N 072601 012130 : bulb : x2

The good news was, I already had all these parts "in stock" on my now-famous shelf. :D

Tools:
assorted screwdrivers, wire cutters, crimping tool.

Here are the items:

"contact bushing"

cable harness

interior lamp (with bulb installed)

The first thing you need to do is alter the cables you bought. Cut the two metal pins off one end, strip the wires and crimp a "contact bushing" onto them instead. Apologies for my appauling crimping techniques ;)

Next you need to remove the door panel. I already wrote this procedure up a few weeks ago, the previous time I attempted to get the stupid door lamps working ;)

HOWTO: W202 facelift front inner door panel removal

Once the door panel is off, locate the door control unit, which is the black box near the door mirror.

Pull the little grey lever down while pressing the clip in on top of it to release the plug.

at the side of the plug is a tiny tab, lift this and all the wiring and the inner-plug can be taken out (Russian dolls or what? :) )

courtesy06.jpg


Push the red and grey wire into pin position 1, and the brown and blue wire into position 5.

courtesy07.jpg


Then slide the inner-plug into the outer-plug and then push the whole thing back into the control box, move the lever back up to the original position to make sure it's securely fastened.

Plug the light in to test!

It works!! :D

Unplug the light and cut a small hole in the plastic sheet near the bottom of the door (near where the lamp will actually be housed). Feed the two plugs and some wire through this.

On the underside of the door panel is a blank where the lamp should be fitted. Pop this off with a screwdriver or your fingernail.

Time to remount the door panel! (see my previous instructions for this process) Take note that you should feed the two plastic plugs and some wire through the hole in the bottom of the door panel before finally clipping and screwing it all shut, which is tricky at the best of times.

When it's all fastened back up and secured again, plug the lamp into the two connectors (doesn't matter which way around) and then slide/clip the lamp into the hole.

Done!

Now repeat for the other side! I'm gonna go do the other side right now myself :) Will post pics of how they look at night :D

Didn't Sym say he had these as standard?

The sort of attention to detail that should be on all our cars :(

Elegance models have both illuminated visors and door courtesy lamps as standard.

As ever, a great post Nick with loadsa pictures to keep the less technically minded (like me :p ) fully informed about the mod. :D

One silly question, I'm assuming the newly fitted courtesy lights fade to black in unison with all the other interior lights as they are controlled by a magical black box?

yeah - got them .... + the vanity mirrors....

....although Steve was looking at my car and telling me that he could get lots of other bits to light up too . . . like the lever under the dash that releases the adjustable steering wheel column (assuming you have one of those as standard too !!!) - don't think i'll be attempting that one though !

nice mod though Shude - at least I know how to disconnect them easily now when i want to take my door cards off properly for the next mod ;) ;) ;)

Nope, the black box turns them on and off without any grace at all! If you want them to fade you will either have to fit a capacitor to the lamp or try wiring them up to the dome light instead. The way I have described is the OEM way, and TBH you will never see the fade on/off anyway, unlike the pre-facelift lamps they only come on when the specific door is opened. I have yet to see how effective they are at night :)

This will work on your car, the parts are from the stealership parts dept. The wiring looms are about £3 each, pins are pennies and the lamps are about 50p each, bulbs about the same. Not bad for a £50+ option! :)

They are very effective at night ... great for avoiding tripping up over all the old mercedes parts in my garage (smelly rubber pedals . . . boring black shift surrounds, non-blinking mirrors :eek: :eek: etc etc ;))

Don't think I haven't been planning it! :)

I think these should do the trick, they are the slightly narrower w124 courtesy lamps. I will try to mount them in the rear speaker covers rather than in the door trim to avoid expensive mistakes :)

It doesn't! If you have a w202 then from the factory you're in the dark basically. Factory locations for the w210 are in the front passenger footwells and in the front-seat-backs for the rear passengers. While changing Marks pedals I found the same w124 courtesy lamp right above the pedals, so that's where the R129 SL has them :)

Well...it's possible that the first owner (if it's not you) asked for them as options, they are just a couple of tick boxes :)

More likely your C36 was floodwired and fitted for all options before leaving Bremen for the Affalterbach AMG factory. I guess they assume when you buy the best model there is in a class you'd like some of the toys, if not all of them :)
