ah cheers dude i had found that but it seems overly complecated lol, when i did my starlets e manage all i had was a number chart corrisponding with a ecu connector block which was numberd, and the numbers showed what each pin was if that makes sence. im hoping this excel sheet is the same? also why dosnt it state an ecu wirign diagram on teh 1994?

 

Oh and try this one

you want daz's emu resources thread. There is a link to another forum where its all photo'd and numbered up nicely.

I can't seem to find it since things were moved around, but ive stumbled accross it, so its deffinately here..

 

forget the emu thread. I reckon its gone. There is a emanage resources thread, but the one im after (emanage ultimate guide) has gone.

 

Early 1.8 Roadster ECU was discussed just recently.

Try here: http://www.mx5nutz.com/forum/index.php?showtopic=51599
And if you stick this link into Google Language Tools, it's the Japanese version of the diagrams (inconveniently all in Japanese, of course).

<edit> Second link seems to be missing. Here it is: http://www.do-da.co.jp/wiring_diagram/index.html
