23-25 Sierra 1500 AT4X AEV Reverse Lamp Harness

This harness is used for adding the Baja Designs 3" cube lights into your rear bumper on your AEV.

This harness is a relay style harness, which will require a posi-loc(t-tap) connection at the positive wire on the trailer connector.  A relay style is needed as the reverse system, does not support the extra load on the circuit.  

Fits 23-25 1500 models.  Comes with the correct connector for the Baja squadron lights.  If you are using a different style light, you can simply remove those connectors from our harness.

Here is a link to the AEV site for the lamps and brackets.  You will not need to purchase the harness from them.

This harness can also be used to power other items you want on with the reverse lights.

INSTALL: Harness will plug inline at either taillight to body harness.  This connection is located at the rear frame rail at either side of the truck.  Disconnect that connector and install the PnP portion into it and connect back together.  At that point you can mount the relay.  The relay does not need to be grounded, we just recommend that you install it where it won't get constant exposure to water or salt.   Once that is done you will install the Posi-Loc.  At the backside of the trailer connector, you will see a group of 7 wires.  2 of these wires are larger than the rest.  The white wire is the largest and the second wire is usually red/green stripe or orange.  This is the wire you will want to install the posi-loc onto to.  Unscrew the cap, opposite the wire side and install the cap over the power wire, then screw the housing onto the cap.  Once you have verified that everything is working you can wrap that posi-loc in electrical tape or apply some silicon sealer to it.  

We have found on some 25 models that there is a black wire and that is actually the power wire, not all models but some.  So if you have a black wire anywhere at the trailer plug, that is the one to use
