That doesn't make a lot of sense...

Do you have a brake controller fitted? Thats probably where the wire in the floor should go to.

Perhaps you could add a bit more detail?

Hi malcolm yes i have a Hayman Reese controler power to 12 pin connector. power to both sides no power to magnets when brakes applied. stupid setup by avan cable runs thu chassis and out to brakes thu floor can't see cable in van. thats why i want to rewire them wire from female plug to both wheels.

Wiring the brakes is pretty simple provided you have power at the trailer plug as you say.
You simply need a fat cable (bigger the better 8 or 6B&S) from the plug run back to the middle of the axle. From that point you run equal length cables out to each magnet. Failure to use equal length cables to the magnets can result in more braking effort to one side.

For plug & socket pinouts use Google. You need to use both the positive and negative brake wires from the plug, not the common lighting negative.

Is there anything else you need to know?

Thanks will give it a go, Avan don't worry about equal lengths one side about a metre other 20cm.
and both wires to magnets are green.

They don't have a + or - so doesn't matter which wire is which.
Equal length wires makes a big difference.

Do you have a good earth return to the car?
This is required to complete the circuit.

You dont need 8 B& S cable for brakes as it will never go into the connector,I used twin 6mm automotive cable and wound them together and had no trouble stopping a 3T van
On connectors from car to van PIN 5 is ALWAYS the electric brakes regardless of whether its a 7pin flat or round or a 12 pin flat. Earth is always PIN 3
As said make sure earth is good right back to car If tail lights are going it probably is.
Look in your connector on the van and tell us what colour wire is on each pin
Not enough clear info really.
Where is wire coming out of floor above axles ? at front of van???
There is only one wire for brakes in the connector and it uses the common earth on pin3 which is earth for everything unless you have something likea fridge wired through an Anderson Plug THEN you use 8 B&S or heavier for that only

Hi tom the cable to the RH brake comes out of the floor 3/4 way above axle is about 2.5 metres long the LH cable comes out on edge of van floor above brake.
about 35cm long.
The brake controller is wired to pin 12 red. earth pin 10 black
plugged into car power to van plug ok.check with circuit tester at brakes no power.
will get twin 6mm and rewire.

thanks

Most unusual and equaly unwise. What brand is the brake controller.
It is always best to adhere to standard wiring connections as should you hook up to another vehicle clouds of smoke could be the result.
Electric brakes only have one wire from the vehicle It is often blue and as I said is ALWAYS ON PIN 5 regardless of the type of connector.
The earth normally is the standard earth wire on pin 3.
You obviously have a 12 pin flat plug and pins 8 to 12 are heavier for the likes of fridges and battery charging but NEVER BRAKES. Also your power circuit in the tug for the brake controller should have an auto resetting circuit breaker in it NOT A FUSE as I saw with a unit sold by Caravans plus.
Fuse blows no brakes Circuit breaker will reset at least.
I notice on an AVan forum they seem to use Scotchlock connectors If your van has them get rid of them The inventor of them should be hung
Read this and make sure you have a proportional one like a P3 or a Prodigy or a Redarc Tow Pro

Hi Tom it's a Hayman Reese controler and there is a 20 amp breaker, have had this in the car for 3 vans this is the first have have problems not with the car. the van will probably get a auto sparky to sort it out.

Which model because some of them are the old type You want a proportional type that applies the brakes according to how fast you are decellerating.
The old type like the Redarc and the Hayman Reece (mostly rebranded Tekonsha) ones you dial up how much you want and thats what you get ALWAYS So if you have it set for a nice dry road and it rains and you dont back it off it will lock the brakes. The proportional ones are much better and safer despite what the "Ive had it for 40 years" brigade say. LOL
It may be that the car has the brake wire on pin 5 (Normal) and the van has it on another one. From what I read on the Avan forum their wiring leaves a lot to be desired. In this linkBrake controllers the outside top two are good ones and the middle one underneath
They are rebranded Tekonsha P3 Prodigy and the bottom one is a Redarc tow Pro The middle top one is an old technology set and crash model

Yes it is a Proportional Brake Controller.
