# Step 11: Wiring the Buggy3
## Task 1: Install FMU power module
Gather the FMU power module:
Plug the power module into the PDB. Route the 6-pin power connector to the top PCB and plug into the FMU POWER port.
You may wish to zip tie the power module to the underside of the PCB
## Note regarding Buggy 3 Battery
{% hint style="warning" %}
Do not use a LiPo battery larger than 2S. Internal testing has reported issues using larger battery voltages than 7.2V in a 2S battery.
{% endhint %}
The Buggy3 can use a 2S in the range of 1000 - 5000mAh. Carefully check which ones will fit in the space available.\
\
The battery should have an XT60 plug end and not the T or DEANS style end.\
An XT60 may be soldered in place (carefully - you must be extra careful to never short the battery pins for risk of fire/explosion!) or an adapter from T/Deans to XT60 may be used.
### Servo and ESC PWM connections
You will also need to connect the two PWM wires from the servo/ESC. The servo PWM goes in slot 2, whereas the ESC goes in slot 4.
{% hint style="warning" %}
Make sure that the GND wire (brown) goes on top. In the picture below, the cable in PWM slot 4 is INCORRECT! Slot 2 is correct.
{% endhint %}
