Well time has come to rewire the cosmo! The standard abacus of a computer isn't cutting it so am upgrading to a MS ( and then FreeEms later ;) )...

I want to map out the standard harness to help others (as it is impossible to find complete diagrams in english for the rotary turbo option), and then of course design a new harness.

Does anyone have any software they could recommend??

Thanks in advance,
Aaron

I don't know about wiring diagram software, but I would be very wary of using OEM wiring with a MS or even FreeEMS one day. It can be made to work, yes, but the oem grounding scheme must be adhered to, and often they use appalling grounding locations and bodgy power feeds too. I would wire along side it if I were you, or replace it all together. Also bare in mind that that wiring is ?? 10 - 30 years old? It's not like it used to be in there. Just a few thoughts for you :-)

Yeah, I am rewiring from scratch. The standard loom and grounds are shocking. Also it has been molested in a few places, so a few things do not work properly.

Most of loom is excess to suit the other motor, emission and interior configurations.

Many people use Microsoft Visio for this kind of stuff. I have a friend who does motorsport wiring and he makes some quite good looking diagrams with it. Its not open-source obviously.

Having said that, i have found Visio quite frustrating at times but that was doing pneumatic diagrams, not electrical. If you're a windows user and have Office Pro then I'd give it a try and see what you think.

There are a few tools for doing code design that you could use for that I guess. Have you done an apt-cache search?

There may be something specifically for it.

I have used TinyCAD for diagrams. I have done micro p boards in it and exported the net list to FreePCB and sent the gerbers to Advanced Circuits. They came out great. Tiny CAD works fine for wiring and other things. There is a easy to use symbol editor too. Its interface is Viso like (more like DOS Orcad) gui that knows netlists and part names and labeling conventions. And they are both free! 8-)

My apologies! So many people with pseudonyms on here, it's easy to make that assumption :-)

Welcome along!

Fred.
