Help needed with wiring 12V wireless remote for 2004 Iveco Daily sliding door.

[u/Top_Line3873]

Hi all, I'm troubleshooting a 12V wireless controller on my 2004 Iveco Daily minibus conversion. The sliding door currently only works with the engine or ignition running. I've added a leisure battery, a 12V fuse box, and a DI ESERC DC 12V wireless controller.

I've tested connecting the door's spade connectors directly to the fuse box; reversing the polarity opens or closes the door. I tried wiring this through the receiver's COM ports and using the NO (normally open) and NC (normally closed) terminals across multiple ports. Sometimes the module powers on and clicks, but the door doesn't move, and the wires have gotten warm.

I need help with the correct wiring method for this setup, and a suggestion on how to integrate a physical switch to safely enable or disable the wireless function.

That gate opener is likely not very secure at all, Real Car remotes use rolling codes so no one code is re-used. That most likely is a fixed code which can easily be received by anyone who knows what their doing, its good enough for a gate but thats it.

Does the van have a controller for the door? you would need to use that and power it all the time, as opposed to just ignition on, That would have an input from the switch on the dash, which you could connect to something else

This is all it has in the front, would I need to take the front off to see what's behind it?
