I am working on an Arduino remote starter project for my 2001 Blazer 4.3 4x4
For safety reasons I need to check the status of several things: door lock position, ignition key in or out, park/neutral position, engine RPM, & vehicle speed. I am assuming that I can read each of these from the E.C.M. but I need a Pinout or diagram to indicate the proper wires to check.
Does anyone have a PDF copy of the '01 Pinout or other document that would help me?

 

Give me vehicle specs and I will look them up and send them to you. I need make, model
You gave the year and engine size. Also 4x4 or AWD.

Here is the body computer, starting and charging diagrams. Let me know if you need something else.

 

Thanks a bunch. Looks like just what I needed.

 

No problem at all. Glad to help.

 

 

 

 

"I require" is not a good way to ask for help, and in another person's thread. AlldataDIY.com will have the wiring diagrams that you need. Jimmy might be different in the specific area of your interest, whatever that is. also could be exactly the same.
