Installation won’t take long, as the module comes with all the necessary wires and connectors. And to install it, you will just need to attach it to the factory harness, as shown. It’s as simple as that!
The connector we need to pull out is a blue CA208. It is located on the back side of the fuse box.
The fuse box itself is located on the left-hand side (at the driver’s feet on left-hand drive cars).
This connector is easy to locate to the touch as there is no other connectors underneath it.
The tab on the connector faces to the left.
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).
Here is the best explanation on how to do that ->
Use double side adhesive tape to stick the module to the internals of the door.
Connect your battery and test new feature. Remember to re-program your windows, so they would close on a long key press.
