91 Miata Wiring Diagram

Does anyone know where I might be able to find more detailed wiring diagrams, in relation to which wires are signal wires from the sensors... I require these details as I am coverting my Mx5 to run a stand alone Microtech ECU setup.. I have pretty much matched all the wired except for a couple which I am not certain about.. and as you all would know or understand that guessing these might end up to be catastrophic if incorrect..

Any help or hints would be greatly appriciated...

Cheers

If you've not already got access to the factory workshop wiring diagrams then this will help:
http://neomiata.com/garage/index.php Madracki wiring diagrams etc

But if you've already got them, then a bit more specific info might help as a few forumites have run Microtechs - indeed it might even be worth searching 'microtech' on here as this might have been answered before. Good luck!

this ecu pinout list might also help:

some possibly relevant microtech threads depending on which microtech you're using:
