The next tricky bit is feeding all the wires through a hole in the bulkhead (not forgetting the rubber grommet - thanks ebay!). After that the fuse and relay holders need securing to the side (and top in my case) of the drivers side footwell:
Sadly the Pilgrim loom is generic, so a number of the engine bay wires need to be shorten, e.g. the RoverV8 starter is drivers side. Not a difficult job, but a shame to un-bind the loom to remove wires.
