Smart Bypass Relay TEB7AS 7 way
Our Part No. ETR02
Manufacturers Part No. TEB7AS
This is designed to be fitted on all modern cars with a negative earth. fitted with an audible buzzer
and an outlet for a telltale light.
Suitable for modern cars with canbus, multiplex or other bulb monitoring systems.
We recommend this is used on older vehicles without bulb monitoring circuits as it protects the vehicles wiring from any overloading or faulty wiring on the trailer.
When wiring this item you do require a 15A fused 12volt power supply.
The relay works by picking up the signals to the lights on the rear of the vehicle and converting them
to direct 12v from the 12volt feed.
This does not draw the power from the lighting circuit on the car which stops any overloads on wiring circuits and is not picked up by the monitoring system on the vehicle.
The relay will eliminate any signals that the car sends to monitor the lighting system.
This works with LED lights and irons out the pulses from a monitoring system.
PLEASE NOTE: This does bypass any systems built into modern vehicles like light monitoring
or TSP (trailer stability program)
