Making new wiring harness from scratch, need help

[Ivan141]

Toyota made a great wiring diagram to use as a base .
What I'd do: take the appropriate wiring diagram for your model AE86, convert it to bmp or some such format and just start erasing wires you dont need.

Staying true to the wire colours will be hard without reusing the old ones. There are so many different colour combo's, and they're not exactly common in the retail market.

And, as has been stated before: please share pics etc.
