A new wiring loom Part 1 - Out with the old

From owning old cars electrical gremlins are the ones that let you down. The wiring on the Ten was original except the modifications to the head lamps, fitment of indicators and voltage regulator for a engine temperature gauge. For this, the loom was cut about and different wires added to suit. 

The build quality of the original loom is great. The loom is clipped to the chassis via brass nuts and bolts with steel p-clips. The cotton harness braiding is a delight and something you don't see now but at 79 years young an update is needed.

My main worry is the full current for the circuits run through the switches in the dashboard. I want to reduce this down to the bare minimum with the use of micro relays. For aesthetics I'm planning to refurbish the original fuse box in the engine bay and locate a new modern unit under the dashboard away from the elements.
