Any auto electric bods out there ?

I am fitting a fuel pump cut off switch as a further deterrent on my 2007 Relay 2,2 diesel and need to know which wire on the pump to split--have tried U-tube etc but no joy .There are 2 elec plugs connected to the pump a green one with 2 green wires and a grey one with 2 orange wires.

look for the 2 thicker wires to power the pump, the others are the sender for fuel level

Haynes manual for the van would be the safest bet, you can access it online fairly cheap and see what the wiring diagram says. I know its an obvious one but I've spent too much time trying to guess the non logical wiring of cars to try anymore!

Try unplugging one and see what happens.

Pump in tank?
Chances are one plug will be pump and the other the fuel gauge.
Pull a plug and see if gauge doesn't work. If it does, try the other one.
Then put a meter on the plug wires with ign on and off. If there's power when on and no power when off that will be the pump

To do the job proper your better off getting an auto lecky to splice into the wire from the ECU that reads the key code,
impossable to get round and a lot more reliable than messing around with the pump.
I always get my vans done this way and never had a problem

Don't think there is a manual for the model.

Bugger, sorry should have guessed.
