The wiring looms are specific to throttle body kits used on the normally aspirated Renault F4R range of engines with all cable lengths designed around this.  They are not designed for running standard inlet types or cars with electronic motorised throttle bodies

However, this loom will also fit many other Renault engines (please ask for details).


The looms feature fully heat shrunk, quality cabling with all plugs having flexible rubber boots. S40 Pro wiring looms are generally available from stock with or without VVT plugs for 4 injector NA engines.


Please contact us for any Turbo engine or other special requirements.

You will require a different style air and coolant temperature sensor from the Renault ones and also a new throttle position sensor if you don't already use a Colvern type with round plug (please see sensor kit for details)


The VVT control is just a switched output as per the Clio 172/182 but does not do closed loop cam phasing as per the Clio 197/200.  You can use a S40 ECU to run a Clio 197/200 with VVT but it will be switched from max to min inlet cam advance and isn't variable.  It will also run a Clio 197/200 with individual coils but will still use a wasted spark set-up firing two coils simultaneously.  If you want to run any car with closed loop VVT and/or sequential ignition/injection then you will need a cam sensor input and a DTA S60 ECU and wiring loom with suitable options.


Before ordering, please see our DTA S40 wiring loom guide/ordering form here

Please ask before ordering if you are unsure about any details or combinations of features available.
