REAR RADAR RECEIVER

(MODELS:  K40-2000/2000P)

1. Choose a mounting location in the rear of the vehicle that is not 

obstructed by any metal, carbon fiber, or chromed plastic. The 
radar receiver can be mounted horizontally or vertically, provided
the arrows are pointing to the rear, towards the road behind the 
vehicle.

2. Mount the radar receiver to the vehicle's structure using the sup-

plied screws or wire tires (see diagram E1).

3. Connect the radar receiver to the 25’ black radar receiver cable.

Align slot on cable plug to the notch on radar receiver socket, slide
the locking ring forward over the socket, and turn ring clockwise
1/4 turn to engage safety lock (see diagram E2).

4. Route the rear radar receiver cable into the trunk through a 

factory grommet.

5. If a factory grommet is not available, use the provided strain relief:

a. Choose a location in the trunk compartment as close to the

radar receiver as possible.

b. Drill a 1/2” hole into the chosen location for the strain relief.

c. Install the strain relief and tighten the mounting nut securely

(see diagram E3) 

d. Route the rear radar receiver cable through the strain relief,

leaving a little slack in the receiver cable.

e. Tighten the waterproof gasket nut to create a water proof seal.

6. Route the rear radar receiver cable through the trunk, into the

passenger compartment along the driver's side, and under the
dash. Connect wires according separately enclosed block 
wiring diagram.

All radar receivers can be mounted behind plastic, rubber, or fiberglass up to 1/4” thick.  Do not mount 
behind metal, carbon fiber, or chromed plastic.
