just done mine with the engine in
take off every thing m8 module's and brackets theres a clump of brake lines at the back of the cross member undo the pipes so you can remove them both, and take out the lines that go to the master cylinder, and to the lines that are left which went from the ABS to each T on the inner wing the wiring with the sencors just unclips
then make up new lines that go from the master cylinder to each T on the wings, the highest line coming out the master cylinder runs to the drivers side lowest to the pass side
