Which fuse are you removing? Thanks Oly

I have recently been thinking about this again and talking to my electrician. Going back to the start... 1) I viewed the car the first time and the reversing sensors worked fine. We agreed a price including having a towbar fitted. 2) A week later I collecting the car and drove the >2hrs home and notch when reversing into the drive the reversing sensors beeped solid for a couple of seconds before going off. The towbar has been fitted with a simple PF Jones kit, spliced into the reversing light. At the time I assumed it was because the sensors can constantly see the towbar. As such I just disconnected the sensors brain box and driven the car without the sensors. However, having recently been thinking about this some more I have taken the sensors out (all are ticking, so working) and even if pointed up at the sky the same fault sound occurs. I was thinking I have two cheap options (presuming the alternative towbar kit is £££?), to reuse the existing sensors with a cheap retrofit reversing sensor kit off ebay, or install the whole cheap retrofit reversing sensor kit (inc new sensors, although they don't fit the same holes) off ebay. But recently my electrician suggested it may be a marginally bad earth. The extra cable installed for the towbar may have been enough to drop the voltage enough to cause the fault to occur if the earth isn't great. Thoughts? Where are the earth points?
