Mk4 Zetec - Rear Fuse Box - Ignition Switched Fuse?


Recommended Posts


Does anyone know if there is an ignition switched fuse on the rear fuse box? I am looking to fusetap into this in order to power parking sensors, rather than power from the reverse light.

Anyone aware if any of those fuses are ignition powered, or are they permanent?

Thanks Alan,

The reason is because I want to be able to use the front parking sensors at the same time, but if I take the car outa reverse, then the sensors all stop...

So I am looking at a remote cutoff switch so that if it starts to beep at me I can kill it remotely.

According to another website, FB1 should be ignition live...

Unfortunately I cannot find FB1 ON Haynes Circuit Diagram amongst a load of other ommissions, the only thing I can suggest is fit the fusetap and check the output with a meter to see if it does operate via the ignition.
