Thank you both rufusking and drivesafe.
the need to remove the body was preying on my tiny mind. I will change the routing for that reason.
Thank you for the information on the flexibility. that is important as you say when trying to run through the route taken for the rear socket wiring.
I will take the inside route.
I will let you know when I have done it. it takes me many moons to do anything so don't hold your breath.
