I want to refurbish the rear light wiring of a campervan. The wiring is a mess with way too many connectors and no labeling, and has intermittent connection issues (lights not working).
On one end, I've got a 4-core cable coming from the van's fuse box. This has to be connected to 6 individual light units (indicator, brake, rear light and 3 contour lights connected to the rear light). The 4-core cable doesn't have a ground so I have a screw terminal on the chassis. The ground has to be split to 6 wires and that's now done in a crazy daisy-chain using a bunch of spade connectors.
For 230V wiring in a house, I'd use these to distribute one wire into several:
but these are for single-core wires while the cables in the campervan all use stranded wires. I'm having trouble finding an equivalent that's suitable for automotive use (it'll also be exposed to the elements, under the chassis). What should I use?
Ideally, I want to clean it up more: get one 12-pole connector on the incoming cable, and 6 2-pole connectors that plug into this. Is that possible at all?
