I want to replace the existing nordekectrica shore charger with with an equivalent victron blue charger. All seems fairly easy and will use dusting positive negative wires. According to manual there seems to be a white connector for temperature sensing, what do people recommend I do about this?

1: leave it there in case I reverse jnstall
2: pull it out at the ecu, my concern is that this may need some jumper switch changes

Thoughts?

As far as I know the white connector is a +12V signal that tells the NE distribution box that the EHU mains is connected. I think it doesn't do anything with that information except send it to the display to show EHU is connected. So if you can live without that, it will be OK. I don't think it's for a temperature sensor.

May be an idea to label the wire in case of future queries. '240V connected (+12V signal)' or similar.

The Schaudt Elektroblock uses that signal internally to switch on a trickle charge to the starter battery, but I don't think the NE stuff does anything with it.

That's correct, the white wire just connects to the main unit which then sends a logic output to the control/ display to show the "mains connected" icon. It doesn't do anything else.
It's a nice feature to retain and this can be done by energising the white cable with 12v from a separate source powered from the 240v mains. Simply a small 12v DC power supply, plug in or whatever. Connect the neg 0v to the common neg somewhere convenient and the output to the white cable via a 1k ohm resistor.
