MMK 61 wiring for PEQ

Hi,
I'd like to know how to correct solder my 61's to the color shown in the wiring diagram for the rainbow2

I've upload this picture to be sure of what I have to do.


If you can just tell me what color (black, red, browm, orange) for each number, it will be so nice !!!
Thanks a lot

Suggest you take your MK75 apart and have a look..

That is exactly what I would like to avoid... but thank you for the advice, if I can't find an answer with the community I will do it
I would also like to understand how it works, it's always better
Actually the 61's was wired as this:
1 to the ground, soldered to the bridge's base and the ground wire
2 and 4 soldered together
3 hot output

the N°1 is positive, the N°2 negative, the N°3 negative  and the N°4 positive

I think I've found by testing the polarity of the MMk 75 without disassembly
COIL whitout screw black wire positive, red wire negative
COIL with screw orange wire positive, brown wire negative
So
N°1 +  to black wire
N°2 -  to red wire
N°3 - to brown wire
N°4 + to orange wire
