I want to completely rewire my car (Marina based Marlin Roadster) and incorporate some of my own ideas at the same time in the harness like headlights worked by relays, all circuits fused, earth circuit etc.
Anyone know of a free to download programme suitable for such design of wiring harnesses ? This is an old technology vehicle so no ecu etc.

Thanks.

Use the free diagrams on http://www.polevolt.co.uk/acatalog/Wiring_Info.html

then just add in what else you need and delete the stuff you don't

I used Tinycad it's a free download and easy to use
Here is a Link
