Habitation door wiring.

I've got 2 wires (black & red) going in a rubber tube fed into my hab door from body.
Anyone any idea what they are for?
Theres no power coming through them when central locking is operated and I doubt the hab door has central locking anyway as its a 06 build ace airstream.
I think youd need at least 3 wires for that anyway ? Earth / lock trigger / unlock trigger ? Theres nothing electric on door so its a mystery without actually removing inside panel of door. Anyone any idea?
Theres no power on body side before rubber gaiter so its not a broken wire issue.
 
Maybe an old alarm cable. Although I would have thought a few small wires. Maybe a radio speaker
Unless you remove the door lining I guess it’s a mystery

Yeah, think I'm going to have to remove and check it out, however it's quite far down the to do list atm.
I maybe need to find another Ace Airstream owner to compare, although there quite unpopular so it might be difficult to find one.

No, doors normal open and shut not sliding? Not sure what a PVC is?

PVC is a panel van conversion, they sometimes have a switch on the sliding door that brings a fan on in the fridge vents if the sliding door opens over them.
Is there a magnet (small white plastic block) screwed to the door or a couple of screws holes where one was previously fitted adjacent to the wires? If so it's deffo for an alarm.
 
I see, no its a coach built motorhome,just not to a very good standard at the moment.
I'll have a look tommorow but I'm pretty sure theres no non factory or retro fitted accessories ever been fitted, theres no extra harnesses or holes/marks where anything has ever been. Good suggestion though. I've had the whole insides to bits fitting LEDs / wiring & changing cupboards , sorting out the plumbing etc and its all been standard sofar.
 
Does it go to the side of the door or the bottom of the door frame.

If it runs along the bottom of the door frame the chances are it could be for electric steps.
 
It attaches to side of door near bottom and disappears into door itself, it feeds off the main wire loom under the nearside sofa.
Its a low door step so the body wasn't designed for electric steps.
I will get a photo today.
I've decided I'm going to have to strip door to investigate as someone mentioned further up posts, it's possible its a door open warning when ign is on ? but if so it doesnt work 🤣

PVC is used universally to mean Polyvinyl Chloride, a cheap plastic. For some reason the motorhome community has started using it for Panel Van Conversions and of course it causes great confusion when someone comes across it used this way. If you Google it you will find page after page of links to plastics but none to panel vans. We need to find something else, how about Converted Panel Van CPV?

PVC is also known as the “poison plastic” and I really don’t want my van associated with it. The plastics industry nabbed the PVC name about 100 years ago and I can’t see any reason to use it differently.

Hmmm, that's odd. I didn't fully understand.
Maybe it goes to the door catch/ lock and performs keyless entry or central locking maybe?

Thats what I thought at 1st, however theres on 2 single cables in conduit and its a fibreglass body so I would expect at least 3 cables, 1 earth and 2 triggers open/shut. Would be nice if it was as I would fix it .

Yes, 3 wires would make sense for sure but I guess they could still do the operation with 2 wires.
Click on click off like a retractable pen.
Reverse the polarity through the 2 wires for a push pull / on off action.

It's quite an old motorhome 07 plate so not sure how modern the tech is on it, but it would be good if it was. Will strip door and look after the million other jobs to do.
 
Could you use one of those small inspection camera gadgets to have a look?
Assuming you have access to one.

Red and Black wires would suggest a +ve and -ve wire, but that is not necessarily the case, just a cable with red and black can be the easiest to source.
I would suspect if it is going into a door that Central Locking is likely to be the purpose. Many Central Locking actuators are two wire systems so not having 3 is not unusual. Also, it is possible that even if two signals were needed, a two-core cable was used and the ground is provided via the metal hinges (unlikely, but possible).
I would also check for the presence of any kind of rounded pin on the door edge - there could be a door open pin sensor for an alarm that has been added? But my money is on Central Locking.

the same "TLA"s are used for so many different things, in different industries and interests, why should PVC be exclusive to mean a type of Plastic?
Just look here for multiple meanings of even PVC (and Panel Van Conversion is not even one of them (yet ;) ))

PVC (disambiguation) - Wikipedia

Your idea of using "CPV" falls down for the same reason - it is already "taken"

CPV - Wikipedia

en.wikipedia.org en.wikipedia.org

Do you really want your van to be associated with violence if you call it "CPV"?

I dare say if you know the make and model there will be an electrical diagram somewhere on line that could help you .

Or even a member with the same Moho.
