Due to technical reasons, the installation of door panels is slightly delayed.
So for now, I decided to install the rear shelf.
Shelf behind the rear seat


Detail #1 - shelf behind the back seat. There were many different types, with different ETK numbers, depending on the year of manufacture, type of seat belts, audio speakers, curtains, brake lights and interior color. But there are three main types - I collected them all :)

Type 1 - up to the year 85 - a flat shelf, under the seat belts of the early type.
Type 2 - 85-87 years - flat shelf, under late-type safety belts
Type 3 - after 87 - shelf with stamping, for late-type seat belts
Type 2 and Type 3 are interchangeable with each other, but not interchangeable with Type 1, due to different seat belt designs. I will write about this later.
Part #2 - bracket (51 46 1 915 535) - 1 pc. For fixing the shelf to the body.
Part No. 3 - outlet nozzle - 4 pcs. Grilles are different for type 1 and types 2 and 3.
Part No. 4 and No. 5 - fasteners for the middle seat belt before 84.
Part #6 and #7 - fasteners for the middle seat belt after 84. On shelf type 1, it is installed on the left, and on shelves of type 2 and 3 - on the right.

Part #8 is an attachment to the shelf, used only for the E30 M3. Photo from the Internet.

The shelf comes complete with noise insulation. We insert clip #2 and screw fasteners #6 and #7 for the middle belt.

We insert grids No. 3. Also pictured are the left and right seat belt covers.

The shelf is ready for installation. But there is also a sun shade in the photo. This is an additional option for the shelf. It is because of it that I install a type 3 shelf, not a type 1, as it should be for an 85.
So,

Shelf/Sunblind


Detail #1 - shelf behind the back seat. The shelf with a built-in blind was type 1 (up to 85 year), or type 3 (after 85 years). Photo from the Internet:

Detail No. 2 - sun shade. For type 1 and 3, it was installed in a special slot in the shelf. On the type 2 shelf, it could simply be screwed from above.

Part No. 3 - left hook (51 46 1 917 381) - 1 pc.
Part No. 4 - right hook (51 46 1 917 382) - 1 pc.
Part No. 5 - bracket (51 46 1 905 393) - 2 pcs. Corresponding part for hooks #3 and #4. Installed in the body.

Curtains for shelf type 1 and type 3 are not interchangeable. They have completely different hooks and corresponding parts for them. For curtain type 1 (before 85), hooks (51 46 1 905 393) were screwed with a self-tapping screw above the rear glass.

And for type 3, above the rear glass, in special holes, corresponding parts for hooks (51 46 1 905 393) were installed.

For comparison, both types of hooks are completely different parts installed above the rear glass.

A shelf with a curtain is ready for installation.


In the photo, the rear speakers are already installed - I will write about them later. There is also a third brake light in the photo. This is another additional option for the back shelf. It was available mainly for the US market.

Let's return to the ETK section
Lighting devices
Third stop lamp


Part No. 1 - brake light (63 25 1 385 187)
Part #2 - P21W lamp holder (63 21 8 355 883)
The lanterns were also of two different types. For Type 1 and 2 shelves, the early lamp was mounted on top of the shelf, and for the US market Type 3 shelf, the late lamp was built into the shelf itself, between the grilles. Photo from the Internet.

I have an earlier lantern.
The back cover of the lantern matched the color of the shelf. I also have it gray.

We screw the lamp bracket to the shelf, and remove the wiring connector that I added to the standard wiring. We insert the lamp cartridge block with the reed switch of the lamp control into the lamp housing.

We snap the lantern onto the bracket and install the back cover so that it does not interfere with the sun shade.
We install the rear shelf in the grooves under the glass and fix it with a clip. The lamp should firmly rest on the glass with its rubber stops at the corners.

We insert the buckle of the middle belt into its fastening on the shelf.

But there is a nuance with the side belts - in this case, they are clamped by a shelf, and will perform only a decorative function, since, as I said earlier - due to their different construction, shelves of type 1 and type 3 are not interchangeable!

In my case, there should be a type 1 shelf with a curtain. But, at one time, I found a shelf with a type 3 curtain. I didn't have back straps at all then, so then I installed it without problems.
So, I installed the shelf now temporarily.
First, it will need to be removed to install the ceiling trim and rear glass. After that, I will also install the corresponding parts for the hooks.
Secondly, I have some plans for her "upgrade" in the future. I already wrote earlier that for type 1 and type 2 shelves, there are factory overhead electric sun blinds that are screwed on top of the shelf. It's not easy to find them, although there is a new one on sale now, but the price of $1000 does not suit me :) And they don't look very good either... Also, I want to install an electric curtain from later BMW models in the shelf. And for this, you need a shelf of type 3 - there is more space under it for the location of the electric drive. I have already installed the wiring and the button - I wrote about it recently. I will also redo the holes for the seat belts, as in type 1, so that they are functional. In addition, there are plans for "music". Of course, then the color of the shelf will be black. Or maybe - blue? ;) For "training", I bought another shelf with a curtain, but I will deal with this after the car is completely assembled. And for now - we have what we have! (c)
