Step by step How do I check my motor plug colour?
How to check which motor plug colour your fatbike has
All you need is a pair of wire cutters and it takes a minute. The colour is on the inside of the motor plug, so you'll need to pull it apart. That's fine: it won't damage the plug.
-
Go to the rear wheel
Put your fatbike on its stand. The motor is in the rear wheel, and one thick cable comes out of it: the motor cable.
-
Follow the motor cable to the plug
The motor cable runs along the frame to the first plug. It's usually held in place with two cable ties. Cut the first one.
-
Cut the second cable tie too
Now the plug hangs free and you can get a good grip on it.
-
Hold the plug on both sides
Hold it by the thick plug housings, not by the thin wires.
-
Pull the plug firmly apart
It's a tight fit, so don't be afraid to pull hard. The plug won't break.
-
Look at the inside
Where the pins stick out you'll see the colour: red or black. That's your motor plug colour.
This controller only fits if the inside of your fatbike's motor plug is this colour. Not sure? You can check it in 1 minute.

Customer Reviews
My V8 Max works again.
This one fitted where the previous one didn't, fine shop.
Same plugs as the original, fine shop.
Handy that it says which plug it is. All top handled.
All the connections matched. The box was completely intact. Really satisfied.
Our V8 Max runs like it used to again. The packaging was a bit battered.
Exactly the same as the original.
Product information
The benefits at a glance
- Restricted to 25 km/h
- 6 km/h throttle
- Original part
- Suitable for: Ouxi V8 Max with red motor cable
- Version: 21A, 250/500W, red motor plug, five connections with alarm
- Speed: limited to 25 km/h, throttle up to 6 km/h, no tuning function
The V8 Max has a bigger battery than the regular V8, but the same motor control with red plug. This limited controller replaces a faulty unit and lets the V8 Max ride like it did on delivery again: 25 km/h assistance and 6 km/h walk assist.
Tuning is not possible with this part; for that there is the tunable V8/C80 controller with red plug. If your V8 Max has a black motor plug, choose the black version. Fitting means moving five plugs over under the saddle, without tools.
The controller drives your fatbike's motor and is usually tucked away in the frame or under the battery holder. Before disconnecting it, take a photo of the existing wiring, so you can then put each plug back in the right place. Always disconnect the battery first before you get started.

Pro tip: first compare the new controller next to the old one and go through the plugs one by one, so you can be sure everything fits before you connect it.

Difference between restricted and tunable: it is in the software, not in the number of amps.
