Default Reverse switch location?

I got me self another cdti saloon auto (primertallic, to match the other 2), last Sunday. Couldnít resist it🙄.
But, because I work away from home, I havenít had the chance to go over it in much detail.
Before purchase, I noticed that the led at the gear stick doesnít light up for reverse gear.
Is there a switch I can check for operation?
Reversing sensors also donít work, so I wonder if itís related to a faulty reverse switch.
There are a few more issues, but Iíll mention in a separate thread to avoid confusion. Ta.

Have you checked to see if the reverse lights come on when itís placed in reverse, if they donít then the likely culprit will be the reverse switch on the box.

Thank for the pointers.
When I got home from work I got a look at it. The light bulb on the dash was lit, so checked that and the rear tail light bulb was out, bringing on the break light.
Tried cleaning the multi plug, but noticed that jiggling the wires to the multiplug would make either or both tail and break light come on.
Someone has put in a tow bar, and joined into the light cluster with those scotch lock connectors. So thatís some wiring to be redone.😣
Couldnít check the reverse lights tonight as I was on me own, but at one point, I did notice the ďPĒ on the gear selector fully lit up. Now itís just dimly lit, so I guess a poor connection somewhere.
Also removed an aftermarket stereo that didnít work, as I suspected it may have been linked to wipers coming on when engine switched off. Wiper problem sorted, so just need to replace the radio now.🙄

could possibly be the gear selector actuator switch on top of the auto gearbox if its an auto. Can take it apart and clean the contacts usually works.
On the kv6 engine the throttle body drips oil right onto the switch.
When replacing, It needs to be set in a certain position to display correctly.
Easy way is to put the car in neutral, rotate the switch slightly until the neutral light appears on stick display.I believe there is a small tool to set it but not really required.
If dodgy it will do a range of things like starting in neutral but not in park, no display lights on certain gears on the stick etc.
If its a manual not sure.

Anyhoo...now checked and reverse lights work, but the led on the gear selector is dim / temperamentally lighting up some times.

Your radio/wipers problem is caused by the switched live and permanent live being the wrong way round.
Common issue with aftermarket radio's

Thanks Ron, I had done some reading about that, so disconnected the radio altogether which sorted out the wiper problem (there was a mess of wires combining the grey plug and brown plug to a common plug, and from that to a single plug that fits to the aftermarket stereo). All different colours of course🙄.
Just donít know which ones to swap around / or how to disconnect them from the plugs.

There was also one green red wire not connected, and another blue/green plug not connected.
