The necessary wires are located under the driver’s seat. You can remove the wire ties for convenience.
We need to connect the module to 3 wires: black, red and white/blue.
The first two are easy. Black to black, red to red.
Note that there are other wires of the same colors on the plugs. You need the black one on the bottom row on the right and the red one on the bottom row on the left (on the grey connector).
