ADS in this picture place it on PCB micro version yes or no? Bit confused
Thank you
Make sure the ads is not there. Then you could add the modular one.

Purple generally means that the 5v circuit is live, but there is no 12v.
Just to check then, I don’t need to plug in the ADS as it’s already on-board, aye? I’m not missing any components (stares at all those empty holes)? 
The empty holes are what are called “vias” (in French anyway), they are used to pass a track from one to the other of the layers of the pcb.

Some of the empty holes are for the option of using through hole components instead of surface mount. Yours looks like mine. As long as you have working voltage regulators installed it should be good.

Yes, all of the needed components for the ADS are on your board.

Are there any hammond cases availiable, which fits the boards?
Micro PCB
part# 1455T2201 aluminum ends
part# 1455T2202 plastic ends (maybe not strong enough and not recommend if cutting box in half)
220 x 165 x 52 mm
This one can get cut in half and used for two PCBs but it looks to me like there’s pretty much no extra length for blade thickness.
edit If you use the plastic bezels with the alum end plates then the box is long to use a 1/8" blade to cut the box in half for two PCBs with a sliver left over. The cut boxes need to be 107 or 107.5mm in length so that the opposite end plate can support the PCB when plugging in the main connectors. (tested by Jake Hunter)
They also make a shorter ones (110mm & 160mm).
Standard PCB
part# 1455Q2201
220 x 125 x 52 mm
Mouser seems cheaper then Digikey. The boxes come with two blank end plates. If you are cutting it in half to make two then you probably should buy the extra end plates. Alum plates are sold in 10 packs and plastic in 2 or 10.
Here’s the list of options at Hammond. Search this page for the either 1455T or 1455Q and you’ll see all the options for that width. The part number is 1455T or 1455Q, then the length options (220, 160, 110) and then the end plate material option (1 - Alum, 2 - Plastic) followed by color codes (blank for clear/grey alum, BK, BU, RD).

Hello, I have to finalize the order of the components that I will be missing from digikey and I am a little lost in the different references. As I don’t want to be wrong, can you confirm that it’s the right ones?
So for the ampseal 23 to be welded, it is this reference that is needed.?
For the male part there are several references and I don’t see any differences on the product page… 
It’s just the color that changes.?
The cheapest can do.?
Are these the correct contacts for the socket?
For the cny172M of the speed pulse output this reference is good.?
Sorry for the “dumb” questions.
Question,
What is the difference between +12V-board pin 20 on micro Amp and +12V-in pin 22 ?
20 is the “+15v” marking which corresponds to the +12v output of the pcb protected against phase inversion by the diodes.
22 is +12v in which powers the PCB from the tractor battery.
Thank you
The 770680-3 has 6 contacts blanked off, you do not want this one, you need 770680-1.
And 776087-1.
I used the same CNY172M, I believe its correct.
great, thank you .
and concerning the contacts, it is the reference 770520-1 that is needed.?
out of curiosity where did you see for the 6 contacts blanked off.?
Yes 770520-1 looks correct, I ordered 770854-1 cannot see much difference other than one is max 1.3mm and the latter 1.5mm.
If you look at the attached PDF you will see the contacts that are blanked off:

If you look closely at the pcb I see 3 LEDs which are soldered but none that come out in the case smce it is a shame to mount LEDs which give information but that it is not visible from the outside
