Well I couldn’t get it in to the van needed a flat bed truck.
It will need a bit of modification with a cutting disc not much about 1/4 inch to 1/2 inch in placesSo they just cut the roof off of the van?
Presumably scrapped it?
At least you know it will fit, and you can look at the remainder when you detach it to know where to cut yours.
I am not sure if I am on the right track here. But if it is to control a motor in two directions by swapping the voltage polarity.so I have ordered some diodes from the internet as ther is only a +- wires I have a two way switch ther is two live feeds in and out that’s fine the up works but the down won’t as the live feed goes directly to negative.
so to isolate the battery when the negative has to be on live to operate the down I am going to put in a diode.
That way ther will be no dead short back to battery I hope.
As a diode is like a one way valve
And the roof should operate
Happy to be told I am wrong as I don’t know to be hones

That went right over my headI am not sure if I am on the right track here. But if it is to control a motor in two directions by swapping the voltage polarity.
Then look at either an H Bridge. OR get a double pole 3 way switch with a center zero, and a momentary action in each direction.
You can the wire a cross shape connection to switch the direction.
If I am on the wrong thing then ignore me. if you need more details give me a shout.
So like that one but not that one so what one ?Like this one. But not this one as is it frequently returned.
Just need to makes sure it is DC rated and the current rating is up to the job.
Sorry Bill. I am on a job right now. I can look for one later this evening for you. BUT I need to know. It is 12V? how many amps does it need to support?So like that one but not that one so what one ?

No switch it’s gone I have a roller shutter door switchWildbill Just a quick question. does the unit not have a controller already with switch gear? Can you take some pictures of the lifting mechanism and electrics please?
I have ordered on worth a punt at just over a tennerif as I suspect you are doing this to power a motor that needs to go in both directions.
And the current draw is less than 20A @ 12V DC.
Then this switch should do it.
I have not bought this myself so cannot give a personal recommendation. But if I was buying for a similar job this is the one I would go for myself.
They even include the wiring diagram for 2 way motors (like an H bridge)
Left one is the one.

The even include the cross over wiring I think by the looks of things.

Still taking it easy ishWildbill you are aamazed at what you are achieving after your health scare.
Only thing with this one it’s very heavy going to take at least for strong men to life on to the roofYou are lucky as mine was caked on with Sikaflex!

I think you will find it's got too much pressure and not enough volume, might blow your connections.View attachment 1088942

So excited the wife forgot to tell me some bits came for the van
The only thing is the pump only supplies 6 ltr per minute
That just over a gallon a minute will that work for showering
And give enough pressure

I have another at the boat I forgot about will get that one suraflow pumpI think you will find it's got too much pressure and not enough volume, might blow your connections.
Not good enough for shower and very un reliable/ short lived speaking from personal experience of 2 I fitted to small bore drinking water taps both failed to self stop completely I fitted external on/off switches,. Definitely not enough flow for a showerView attachment 1088942
