Kaboo Mantis 800w x2, minimotors controller installation with switchboard, can someone please help me?

[Erik Öst]

Hey everyone!

Im looking for someone that could help me with some things. I am trying to install a new controller on my mantis 8 pro, but there are some wires that i dont know where to connect. 

I ordered this controller to be precise:https://de.aliexpress.com/item/1005003173221380.html?spm=a2g0s.9042311.0.0.77ad4c4dBjmlri

When I opened up my mantis/inspected the battery and other parts, I noticed another part in there that I didn't notice from my reading online about the problem with controllers. Im talking about this (HUB/Assembly board below:

Well. A Lot of cables are already hooked up to this board, and I don't really remember which ones I removed or if I removed any from that board ,(when I took out the old controller for inspection). I do know how to connect power and the motors.

 My questions are though really simple:

• Do any of you have any guide for me to follow regarding the wiring from the new controller-unit, and for the "HUB/Assembly board"?

• If I can't figure out where some 2 pin-connectors go, or any other connector goes, will I shortcut the new controller and damage it if I connect anything to the wrong spot? Do every wire need to be put right from the beginning, or can I try switching around until I get it right?

• There are one single black cable, and two red/black 2-pins that is supposed to connect the two controllers, according to this video: https://support.fluidfreeride.com/hc/en-us/articles/360051404772-What-are-the-connections-inside-my-single-motor-Mantis-8-deck-main-switch-box- The problem is that i dont know where to put them, and i dont want to risk trying around with these two red/black cables if i risk to damage my new controller..  

Well, sorry for the long post! I don't know where to turn. There is not much information on the internet. I would be very happy if you could help me in some way. 

Cheers, and have a good day.
