Someone please check something on their 107 for me

This is a continuation from yesterday's rear PASSENGER side marker failure question.

Daniel, Thanks for checking for me! I took the assembly apart and found that the bulb is indeed a seperate tube bulb.

I traced the positive Green and White lead from the light and found that it terminates at the Number 8 post where the electrical supply plug connects. However there is no connection in the plug as seen in the pic below. Perhaps someone disassembled at one time and put it back together the wrong way. Can someone check to see if their plug has an empty number 8 socket? if it isn't empty could one unsnap the plug and tell me which wire goes to socket 8?

To check just take the Passenger Side rear light assembly apart as if checking your blinker or brake light bulbs...two thumb screws.

BTW, the driver side is setup differently. :-)

Many thanks in advance!!!!!!!

Thanks Peter!

Now I'm confused. How can the rear SIDE (corner) marker light get power if this socket is empty?

As a temporary fix I jumpered the positive lead from the rear marker least it got me through inspection.

THere is no lead or socket on #8 I tried to post a picture but I'm having trouble. If you like I can email picture .

Are you saying that your plug is different than mine? In my pic I have a pointer to Lead number 8 which connects via the Green/White wire to the positive on the marker lamp prong.
I also have a pointer to the empty mating socket.

BTW, my email is

Thanks again for your help.

Note: Please make sure your looking at the passenger side as each side is different.

Thanks to Peter we have pics of his '72 350SL. Apparently the wiring is different. I'll post for future reference and for the benefit of others.

Anyone with a 380 or newer to compare to? Your time to help solve this problem is appreciated.

Rick, just pulled the cover on passenger side tail lamp assy on my '83 380SL...#8 hole is Empty! pin on the block , no cage in socket.

RickM 10-27-2003 02:16 PM

Thank Dawg!

Apparently my connector is different from the rest. I'll rewire so Pin 7 supplies power to the marker light.

Thanks again.

Bump...can anyone tell me which wire supplies current to the Passenger side rear marker light?

I have checked the right rear light assembly on my 85 380SL and found as was stated above, no connector use of socket number 8. No pin is present. Looking at a wiring diagram I have it looks like the number 7 socket feeds the marker light usuing the WT/GN wire. I have attempted to insert or attach a copy of the diagram but have not been successful. Is there a help page which explains how to insert or attach an image?
