The CC-688 T-Box flashing light turn lamp output defaults to high-level positive output by default, which can directly drive the output current of 10A to drive the left and right turn lights (there are two wires to connect the left and right turn lights respectively). For some vehicles, the drive line of the turn signal is not easy to connect. Then the flashing lamp switch (red hazard warning flashing switch) control wire can be connected to flashing light turn lamp output wire to  control flashing light for flashing finding car function. This control line is generally low-level negative trigger.

CC-688 T-Box flashing light turn lamp wire output can be changed from high-level positive output to low-level negative output. Before installation, please confirm whether the flashing lamp switch (red hazard warning flashing switch) control wire is positive or negative trigger. For negative trigger, modify the main box flashing light turn lamp output to low-level negative output by the following way, open the case, change the PCB connection J31 & J30 with soldering can change the flashing light turn lamp between positive and negative:
