Tips for replacing wiring harness. Solid state relay box?

[dalla]

Hi guys
I am building a Renault 5 GTT Hill climb car.
The car has previously been raced, but it is somewhat of a hack job.
The wiring harness is totally ruined. Both the engine harness and the dash harness has been severely cut and messes with.
It is virtually impossible to get a new harness for these cars. So I am contemplating making my own.
I am looking for some tips on making a basic race spec wiring loom. Thinking I will run at stack dash. I am thinking of making a separate engine loom for ignition, cooling fan etc. And then another stand alone harness for all the lighting, wipers etc.
I am looking for some inspiration and tips on how to do this? Is there any solid state relay boxes available for race cars?
Thinking of something like the Motogadget M-unit used on many custom motorcycles.

Would it not be cheaper just to have yours repaired?

It's beyond repair mate

Take a look at www.infinitybox.com I used this to wire a kit car. It was really easy with a canbus and many pre-programmed features.

Exactly something like that I was looking for. Quite expensive though. I like that EZ wiring too. Might also be a possibility. Car is road registered by the way, so will need lights etc..
