hi could anyone please give me an idiot proof guide to wiring in an x25xe into a 2.0 dti astravan, yes i will openly admit i am an idiot when it comes to wiring.
i've read the guides and had lots of help and advice from some great people on here, but just when i think i've got it all worked out in my head someone says something and it completely throws me off course.
basically i know what i have to wire into the x7 plug from the vectra engine, but what i don't know is where do i actually join it into my existing wiring? i am guessing that the grey plug under the relay box is where the engine loom plugs into the car, i cant just unplug this and make my connections there because i've got to leave the astra ecu plugged in to run the temp sender and gauge. so do i just remove the specific wires i need from this plug to connect to the x7 plug? if this is the case where or how can i find which wires i actually need?
also as my van is currently a diesel will the wiring for the pump already be there and will there be a connection in the engine plug for this?
any help would be amazing
