I am entirely hyped over my xrgb-mini Framemeister purchase, which I should have in a matter of days (tracking has it in my city but not in my possession yet

Reading up prior to purchase I found the XRGB-mini only comes with a JP21 to 8 pin din mini, but all of my consoles use scart for RGB to my Sony TV currently, as I've never needed or had to buy a JP21 cable.. So I want to make my own euroscart to 8 pin mini din. It seems some people on this forum have either purchased or made their own cable - so can anyone confirm if the following wiring is accurate and will work.
DIN PIN | SCART PIN
1 | 2 (right audio)
2 | 6 (left audio)
3 | 20 (CSYNC - I am not using a 75 ohm resistor as of yet.. do I need?)
4 | 4,5,9,13,14,17,18,21 (GND)
5 | - nothing, not used afaik...
6 | 7 (blue)
7 | 11 (green)
8 | 15 (red)
I have made this cable, but don't know if it works yet..
Consoles I will be using:
famicomAV + rgb board by etim / or original famicom with composite only (no scart)
megadrive with region mod
super famicom
so if there is someone out there who has made this cable with success and or owns a purchased cable which works, can they confirm if this is accurate and will display a picture and provide audio. I am not using a LM1881 or 75ohm resistor or any capacitors at the moment, if needed I am happy to get anything I need.
thanks for any info / advice / comments

(sorry for ruthlessly googling and pasting these image links)
edit: I will probably just alter the JP21 socket to become a Euroscart plug as found here - https://amazingdiy.wordpress.com/2015/0 ... r-modding/
