In Car wiring How to?
In a few weeks time I shall be replacing my front section headlining for a full length La Salle version, and I shall be adding in stereo, speakers, additional lights inside etc.

I've not done any automotive electrics for some time, can anyone give me any golden rules or best practice tips, how to articles etc?

What sort of kit does a DIYer like me need? I still have my old crimp tool, but should I be learning how to do soldered joints etc instead.

If I were to add a set of spotlights for example, I have no real clue whats involved and how to wire them up, but I learn quick.

Thanks chaps 2016 D4 HSE

This may be of some use to you for spots at least

Just make sure that anything that is permanent live (direct from battery) is fused. For example two 100w spots would require 1 x 30amp relay and be fused with a 20amp blade fuse as the power consumption they would use would be roughly 16amps.

Here is a good how to for crimps - I would read this before resorting to soldering stuff:

strong and reliable crimp joints

It is also worth buying the correct thinwall, multistrand wire in sufficient different colours to allow you to differentiate circuits correctly - there is nothing worse than coming back to it later when it is all in red and black, or worse all one colour!

The likes of VWP or Polevolt are good suppliers...

Draw a diagram and keep it safe so you can work out what you've done at a later date.

Also highly recommend thinwall cable of the correct rating, and using lots of colours to separate different functions.

eBay is good for selection packs of cable, connectors, tools etc if you don't want loads.  1988 90 Td5 NAS soft top
