Step 1:

Locate the BCM, which is found under driver side of the dash in the middle. Remove the far left gray connector. To unlock the connector, push the two dark gray tabs towards one another and pull the connector outwards.

Step 2:

Identify the wire in pin location A5 on the gray BCM connector. Based on the dark grey tab being on top. Pin A5 is located in the top row, fifth slot from the right. Wire color may vary between vehicles, therefore, pin locations should be your primary reference.

Step 3:

Utilizing the T-taps provided, attach one to the corresponding wire found in slot A5. Make sure to completely close the T-taps for a proper connection.

Step 4:

Identify the wire in pin location B2 on the gray BCM connector. Based on the blue tab being on top. Pin B2 is located in the top row, second slot from the right. Wire color may vary between vehicles; therefore, pin locations should be your primary reference.

Step 5:

Utilizing the T-taps provided, attach one to the corresponding wire found in slot B2. For additional leverage, pliers can be used to close T-taps.

Step 6:

Once both T-taps are installed, find the blue ring end on the module. The blue ring end needs to be plugged to the wire tapped into pin A5. Proceed to bend the flexible module to connect the other T-tap.
