AE86 engine harness help ..

[eight-six]

Ok I need a stock, uncut engine wiring harness for my AE86.

My car currently has a Zenki set up (3 yellow diagnostic ports) and to save any fuss I want another one to replace the chopped up shit the japanese fitted to my car.

Thing is I cant find one, however the Kouki loom (1 black diagnostic port) seems pretty common and I have the possibility of 2.

Is there a way to get a Kouki engine harness to work with a Zenki setup or is it a case of bodging wires etc.

Can anyone advise what wires / feeds go to the connector on the rear of the engine bay? RPM / temp / oil pressure etc?

Alternativley do I also need the Kouki underdash harness to get everything to work properly?

I have literally got to the end with this car and the stupid parts for it which are stupidly difficult to come by. Quite seriously if I cant get it running properly in the next month or so I will walk away from it or break it.



Cheers

James
