8085X Pro Scale Advanced Lighting Control System

http://www.traxxas.com/manuals

The Traxxas Pro Scale® Advanced Lighting Control System for your TRX-4® Sport consists of two major electronic components: the Pro Scale Lighting Power Module and the Pro Scale Lighting Distribution Block.
The Lighting Power Module installs on the chassis and performs as the voltage regulator and power supply for the lighting system. It also controls various lighting functions through the two buttons on the face of the module and communicates with the receiver in the model via the communication cable or the optional included MAXX® Link cable.
The Lighting Distribution Block mounts in the body of the vehicle and is the distribution hub for all the various wired lights in your Sport body. Its main function is to direct power and instructions to the brake lights, reverse lights, turn signals, and high/low beam lighting.
There is only one rugged breakaway wiring connector between the Lighting Distribution Block and the Lighting Power Module for reliable lighting performance, plus it makes it easy to remove the body for vehicle service. The connector is designed to break away from the vehicle, without damage, if the body comes off the vehicle in a crash. There are lighting channels on the Lighting Power Module which allow the lighting installed on the chassis to be permanently connected and integrated into the system.
This is helpful to install features such as rock lights, bumper lights, and other chassis-mounted accessory lighting.
LIGHTING DISTRIBUTION BLOCK

CAUTION: RISK OF INJURY!
Use care with hobby knives, tapered reamers, and other cutting tools as they are extremely sharp and can cause severe injury, deep cuts, and/or punctures.
CAUTION: RISK OF DAMAGE TO BATTERIES!
Always disconnect the battery from the ESC when not in use to prevent the possibility of over-discharge and battery damage.

LIGHTING POWER MODULE

COMMUNICATION CABLES
Your Pro Scale Advanced Lighting Control System includes two communication cables: the Receiver Communication Cable and the MAXX® Link Cable.
Since your TRX-4 Sport is factory equipped with the TQ receiver, use the Receiver Communication Cable to connect the Lighting Power Module to the receiver.
The MAXX Link Cable is only for use on models with the TQi radio system.
The 6511 Traxxas Link Wireless Module (sold separately) is required for Traxxas Link App functionality (only with the MAXX Link Cable). Some models may require a software update for the TQi receiver via the Traxxas Link App for custom lighting controls and configurations (see Appendix on page 7 for additional information).

A. INSTALL THE LIGHTING POWER MODULE ON THE CHASSIS

1. Install the Power Module mount on the chassis with the included 2.5x10mm countersunk cap screw (Fig. 1).
2. Install the Lighting Power Module on the mount with the included 2.5x12mm (1) and 2.5x18mm (1) cap screws (Fig. 1).
3. Route the module power wire under the mount. Plug the red male connector from the ESC into the red female connector from the power wire (refer to the Chassis Wiring Diagram on page 3 for more detail).

B. WIRE THE LIGHTING POWER MODULE TO THE RECEIVER

1. Plug one end of the Receiver Communication Cable into the RX IN port on the Power Module (Fig. 2) (refer to the Chassis Wiring Diagram on page 3 for more detail). Fig. 2

2. Remove the 3x10mm counter-sunk cap screws (2) from the battery tray (Fig. 3).

3. Lift up the battery tray and route the Receiver Communication Cable from the Power Module under the battery tray and to the receiver box (refer to the Chassis Wiring Diagram on page 3 for more detail). Use a zip tie (included) to attach the wires to the loop on top of the transmission housing. Reinstall and tighten the battery tray screws. Note: Be careful not to pinch or damage any of the wires under the battery tray.

4. Remove the receiver box coverby removing the three 3x8mm button-head cap screws (Fig 4).

5. Remove the wire clamp by removing the two 2.5x8mm cap screws (Fig 4).

6. Feed the loose end of the Receiver Communication Cable connector over the wire guide and into the receiver box (Fig. 5). To make installation easier, unplug and remove a few of the existing wires from the receiver box. Note the locations of any unplugged wires.
   Use needle nose pliers to help grab the connectors and pull them through.
   Arrange all wires neatly between the wire guides in the receiver box (Fig. 5).
   The excess wire will be bundled inside the receiver box.

7. Apply a bead of the included silicone grease to the wire clamp (Fig. 6).

8. Be careful not to damage the wires (make sure the wires are in the wire guides). Reinstall the wire clamp. Tighten the two 2.5x8mm cap screws securely (Fig. 7).

9. Unplug the electronic speed control (ESC) from the receiver (channel 2).

10. Plug the communication cable into the receiver (Fig. 8): the black connector with the single blue wire plugs into one of the channel 1 ports; the female black connector with the 3 black wires plugs into the channel 2 port.

11. Now, plug the black male connector (white, red, black servo cable) from the ESC into the black female connector (white, red, black servo cable) on the communication cable (refer to the Chassis Wiring Diagram on page 3 for moredetail). Leave the steering servo cable plugged into the other channel 1 port.

12. Make sure the blue o-ring gasket is properly seated in the groove in the receiver box so that the cover will not pinch it or damage it in any way.

13. Reinstall the cover on the receiver box and tighten the three 3x8mm buttonhead cap screws  securely.
    Inspect the cover to make  sure that the O-ring  seal is not visible.

14. Use the supplied zip ties to bundle the wires neatly and attach them to the vehicle as needed so that loose wires will not become entangled with moving parts.

C. WIRE THE FRONT BUMPER LIGHT BAR TO THE POWER MODULE

1. If the front bumper light bar is installed on the chassis, plug the light bar wire harness connector (black wire  only) into the includedhigh/low adapter (Fig. 9).

Some lighting equipment shown sold separately:

E. MODIFY THE BODY

1. Install the included templates on the body. Align the arrows with the body lines on the front grille and the tailgate as shown in Fig. 12 and 13.
2. Using a tapered body reamer, carefully cut the holes in the truck body for the screw bosses on the front grille retainer and the tailgate panel (note the hole diameters indicated on the templates and the corresponding diameter  measurements on the body reamer).
3. Using a hobby knife, carefully cut out the holes in the truck body for the headlight housing and the tail light lens.

Tip: If you have a rotary tool (such as Dremel®), then use a small routing bit to cut out the openings. Start by using the tapered reamer to make a small hole inside the area to be removed. Insert the routing bit into the hole, and then follow the cut out lines.
CAUTION: Wear your eye protection when using the motorized tool! Use a hobby knife or a small file to carefully trim the corners square. When using a hobby knife, score the body material several times with the knife blade, and then snap it over to break and release. This will provide the cleanest cuts. Do not try to cut all the way through the body material in one pass or “saw” it with the knife blade.
CAUTION: RISK OF INJURY!
Use care with hobby knives, tapered reamers, and other cutting tools as they are extremely sharp and can cause severe injury, deep cuts, and/or punctures.

F. INSTALL LED LIGHTS
Note: While installing the LED lights, install the included zip tie mounts and use zip ties to secure the wiring to the body in the locations provided (refer to the Lighting Assembly Diagram below and the Body Wiring Diagram on page 6 for more detail). The zip ties do not need to be tight; allow some slack for wire movement.

1. Install the front grille (A) with the front grille retainer (B), headlight clamps (C), tailgate panel (D) with the tailgate panel retainer (E), and tail light clamps (F) on the truck body using the included hardware.
2. Insert the headlight LEDs (G) and tail light LEDs (H) into the receptacles of the headlight clamps and tail light clamps. Be careful not to damage the wires. The LEDs should snap into place.
3. Insert the reverse light LEDs (I) (harness labeled for distribution block port A) and turn signal LEDs (J) (harness labeled for distribution block port B) into the receptacles in the tailgate panel. The LEDs should snap into place. Route both harnesses alongside the existing wiring in the truck body (see Body Wiring Diagram on page 6 for correct LED locations; reverse lights to the inside, turn signals to the outside).
