TIP: refers C2 only
Never try replacing the pump cable back to micro switch unit you'll have to take the whole unit out to do that. Just cut the old wire and splice to the new pump wire using heat shrink sleaves obtainable in some auto shops. Watch the wire with thin trace colour [eg: white with black thin tracer colour] no matter if the wires are different colour make sure that you joint the wires with tracer colour on the old pump wire to the wire with a tracer on the new pump,then obviously join the two plain ones together.
