Old earth was cut off and loom taped up, I dispensed with the whole of the original stuff, apart from using the red/black wire to feed the new relay located in the boot, other end of black/red that came from original relay was chopped at relay, and joined to my emerald K3 ecu as this feeds the fuel pump, took out the oe relay and job done, made a simple loop[ of wire with a male spade on each end, in case of relay failure, can always bridge 30 and 87 so the pump runs continuous, also good for fault finding at times.
