Hi there welcome and thank you for the question hope i can be of some assistance to your problem
I'm just trying to get a clear idea of what you are wanting to do, you are removing the rear doors but this is causing the door open light to come on and i take it the rest of the central locking will not lock as it thinks the rear doors are open so you want to make the vehicle think the doors are shut?
Can i have the reg of your vehicle?
Thankyou for your reply reg no is YS08UFE .
Ok then behind the drivers side rear light unit will be two plugs a grey and a black one now these plugs are what the wiring in the rear door connects in to.
What you need to do is earth out three wires in the black plug and it will make the module think that the rear door is lock so the central locking should work ok and the light on the dash should go out but do one wire at a time.
The first wire colour is a yellow / orange wire this is for the door ajar warning light.
The second wire is a green / violet and this is for the lock / unlock switch status.
The third wire is a either a yellow / blue or the white / violet wire which is for the set / reset switch so just try one at once to see which one does the job.
Give this a try and let me know how you get on.
Hello again thankyou for info i will try what you say i think you are right can i ask about same van if i fit a towbar do really need a dedicated canvan relay or can i connect into wiring loom at tail lamps as i have done in the past some people say yes i can others no would like your opinion just a normal 7 pin socket for small trailer thanyou.
You can go directly into the rear light but you should really use a 7 pin by pass relay and not go directly into wiring onto vehicle just so no problems are caused the relay is in the link below.
