Warnings: Overloading circuits can cause fire. DO NOT exceed stated product ratings. Read vehicle’s owner’s manual and instruction sheet for additional information. Do not operate the converter if defective or if the case or wires are damaged.

Install Instructions: This solid-state version of the converter (TM3-TDW06-US) is made for trailers with LED lights. The max load is 2A on all 3 circuits (that is max 2*12=24W total). Check trailer lights specifications before installing.

Structural Integrity: The converter is encased within a sealed box. Inspect the box for its structural integrity. DO NOT INSTALL the converter on the car if the case is broken, the USB cover was detached, or in any way that the case is improperly sealed. Please, contact us and describe the problem. Do not remove the screws and do not open the case. Do not remove the USB plugs unless you plan to perform a software update. This is normally unnecessary.

Testing aside from the car (Not required): The converter was tested successfully before shipping. However, the converter can be easily tested by powering it with 12VDC power supply or a battery, if available. The 12VDC can be applied on the 2 side tabs of the connector that is to plug into the car. These are marked + and – on the case on the connector side. Make sure not to reverse the polarity, it may damage the electronics. The center tab is for the Data and should be left disconnected. An LED inside the case is visible through the bottom side of the case (opposite side of the engraved label). Being in a shaded place makes it easier to see. Immediately after being powered, this LED will blink quickly several times for about 1s. Then, the 3 LEDs on the trailer connector should blink in sequence (1-3-2, Lights-Left-Right). To repeat the test, simply remove and apply the power again.

Testing your trailer lights (Helpful): If you have the 12VDC power supply that you used in Test 1, you may also use it to test your trailer lights, to make sure the trailer LEDs are working, and the circuits are not shorted.

Testing at the time of mounting on the car (Required): If the taillights of the car are disconnected (as they normally are when you remove the bumper to install the hitch receiver and gain access to the Tesla trailer connector), connect them back before testing. Plug the converter into the Tesla trailer connector, all the way in until connector latch is engaged. Provided that the Tesla is awake, the same as in the Test 1 above should happen, inside LED should blink followed by the 3 LEDs on the black connector. Then, command the turn signals, lights, and brake lights. The respective function should be shown by the LED on the 4-prong connector. These are marked on the connector as RT=Right Turn, LT=Left Turn, TM=Taillights. Finally, plug in the trailer (LED lights only, incandescent will probably overload the circuit) and check the functionality like above (turn signals, lights, and the brake) on the taillights.

Installation Place: The case of the converter is made to be watertight. However, it is good to install it in a place that is as dry as possible.

• Option 1: The converter may be mounted (attached with plastic ties) under the bumper fascia above the bumper, where the Tesla trailer connector is located. However, this place is not accessible after you replace the fascia.
• Option 2 (prefered): If you plan to have access to the adapter (and be able to remove it without removing the fascia), it is possible to pull the Tesla connector below the bumper and install the adapter below as well. However, this place is lower to the ground, so at a boat ramp for example water may accidentally reach the converter and its connections. This option is preferable because it allows you to remove the module when not used (do not discard the cap that comes on the Tesla connector so you can set it back when you remove the module) and have immediate access to it, should a malfunction occur.

TROUBLESHOOTING: The converter includes an electronic fuse. If a trailer side circuit is shorted all lights are temporarily disabled. The converter will reattempt the connection in approximately 10s. If the short persists, the circuits will be disabled again. If this is the case, disconnect the trailer from the module without delay. The LEDs on the black connector should resume their proper function

If in any case the trailer lights are not properly working, unplug the trailer and check the functionality on the black connector LEDs. If these LEDs are not properly functioning, unplug and plug back the module from the Tesla connector. If Test 1 does not pass, please contact us.

Please let us know if you experience any problems.

Note: Tesla Model 3 also includes circuit protections that may sense short or overloaded circuits. If that protection is triggered, the car will stop the power on the trailer connector. The power should reset itself in about 30min (provided that the short condition was cleared).

Software updates: The converter includes a USB plug that is covered with a plug. The USB port may be used for future software updates, in the unlikely event that an update becomes necessary. Do not unnecessarily uncover the USB plug as this may deteriorate the seal.
