AE86 engine harness help ..

[eight-six]

Hi Jondee, thanks for the link, very useful!

I suppose the question that remains is:

If I got a late spec wiring loom and isolated the cables listed and sent them to the firewall connector the loom would it work without issue?

On a late spec loom do the listed cables run back to the ECU or do they connect up under the dash somewhere?

Do you have any idea on how the pin outs for the early spec loom and the late spec loom compare when they plug into the ECU?

Cheers

James
