Sorry for late reply.
Right, all looms are LHD, there are no RHD looms.
What I did was simple, on the original looms you get with car from new are LHD and RHD depending where you are in the world, The aftermarket loom is only LHD, so you need to do this, usually the controller is under the passenger side on RHD vehicles, mine is under the drivers side LHD spec, all you need to do is swap the seat looms over L to R, if that makes sense?
I did not cut or extend any loom, the long part goes to the passenger side and the short part is the drivers side.
Any problems let me know and I will assist.
