Does anybody have the ability to tell me exactly how the ECM interacts with the running of the 22r carbureted pickup. From ignition to actually driving how does it function what does it do how do you wire it anything that you can tell me. ECM part number is 89550-35300 California model. I'm contacting Aisin Monday.

This is all just so I can figure out exactly how to wire it and get the truck up and running finally calculating the wiring and stuff is not what I need I just need to know what the functions are. And the reason why I can't just find anything online is because the only thing I find online are things that include an AC system which I don't have for instance.

And please no more just telling me I'm not focusing on the right area I have to do this in my own way I have to learn in my own way if you can't answer the question please don't bother. I'm disabled and I'm a stubborn sob. Explain it like you would explain it to somebody with autism because technically I have that.

 

I can't tell you but I can show you in a way that you can take it in at your own pace. Here's a link to an online PDF file of the Toyota 1985 Pickup & 4Runner FSM (Field Service Manual).
Start at page 136. It shows a diagram of the ECU and what it's connected to, plus some text tables later that explains what is going on under certain conditions.

I'm also going to post this link in the 84/85 category on it's own.
