I tried to make it as modular as possible.
The cable harness will be fixed to the chassis only so that it can be removed in it’s entirety by simply disconnecting some connectors.
So the harness will have a fuse and relay bay, a loom running to the dashboard, to the aft lights, front lights, and a power section running to the battery and ignition key. Then there are only a few wires left to hook up the horn, and some sensors in the engine bay.
I selected the super seal connectors for the job, they are not the cheapest but they are quite durable and made for automotive.
