If you started with a ARL AE86 (Australian specification) then you will want to keep most of the loom just the way it is. The loom is fairly basic and light as it is. And you need almost all of it.
The only things you wont use are:
- 1 wire to auto choke
- A/C wires and switches
- wire to rear wiper
- rear wiper switch and water squirter
I think it's better to leave the loom as a uncut part in this case.
