- Ensure connectors are fully inserted with locking tabs in place.
-
Route and Connect the T-Connector (Driver Side):
- Route the T-Connector end with the yellow wire to the driver’s side, behind the panels and along the threshold.
- Repeat the connection process on the driver side using the T-Connector containing the yellow wire.
-
Establish Ground Connection:
- Locate a suitable grounding point near the connector.
- If no existing ground stud is available, drill a 3/32" hole and secure the white wire with the eyelet using the provided screw.
- Alternatively, on the passenger side, locate an existing ground stud, loosen the bolt, place the screw eyelet on the stud, and re-tighten the bolt.
- Locate a suitable grounding point near the connector.
-
Mount the Converter Box:
- On the passenger side, mount the T-Connector's black converter box in an out-of-the-way location using the provided double-sided tape.

Safety Notes:
- Before drilling, verify that there are no hidden items behind or under any surface to avoid damage or personal injury.
- Ensure all connectors are fully inserted with locking tabs in place to prevent disconnection.
- Secure loose wires to prevent contact with moving parts or hot surfaces.
- Avoid routing wires through areas that may cut or pinch them.
Warning: Do not exceed the product rating or the tow vehicle's lamp load rating, whichever is lower. Exceeding these ratings can lead to loss of warranty, overheating, and potential fire.
