easyer than that mate, you can cut back you engine bay loom (starts at the fuse box at the back right of the engine bay, runs lights ect aswell.) cut all the engine sensors out bar the gearbox sensors and fan switchs and the coolent sensor (this tells the ecu what to display on your clocks)

then its 7 wires to put your frst loom in,

standard pumps are pretty good tbh so ok to start with.
