I was gonna re route mine but my side skirts arent going to come off easily. the bodyshop riveted and sealed the lines to smooth it all in. you need to remove the arch and skirt to get access to move it.
could always chop them all and solder the all back together once rerouted in engine bay i suppose. just this will look ugly in the engine bay.. best way i have seen is cable tie them up out the way.
