For Vans with "Slave" relay on flasher circuit
This is one of the most versatile plug-in flasher monitors available. 
It combines the excellent monitoring circuitry of the TF2000 series  with an unique system that copies the pin formation of any relay using the standard 3/4/5 pin pattern. 
Like the TF2005  it monitors the current coming into pin 49 of the flasher relay but does so without the need to cut any of the vehicle's wires.

In most modern cars, the flasher relay can be found in the fusebox or somewhere equally accessible. The design of the Clone enables the fitter to remove the flasher relay, adapt it to monitor the presence of an active trailer flasher circuit, and plug it back in again with no "wiring" necessary.


The diagram below illustrates how it is fitted.

The clone moulding has pin support slots that conform to the standard 3/4/5 pin pattern; when the device is being fitted, pins of standard dimensions, connected by wires to the pins of the vehicle flasher, are fitted into the moulding in an exact imitation of the pin-out pattern of the original relay. Between the Clone and the original relay, however, a monitor circuit is introduced, effectively converting the flasher into a "caravan" flasher relay, capable of detecting the presence of an active trailer flasher system.

The small footprint of the clone moulding means that it will fit into virtually any relay space. Another specific advantage of the Clone is that not only will it add an extra telltale output pin to activate any built-in trailer flasher telltale panel lamp but, where there is no built-in tell-tale panel lamp, connection of a new panel lamp or buzzer is made easy by the presence of a spare earth wire on the monitor. 

All connections are made "on the bench" and the only work that has to be done in the vehicle is the removal of the relay at the outset and the plugging in of the made-up clone assembly on completion (plus the fitting of the new panel lamp if applicable).
