When reading a pinout of the plugs on a ecu do you look at the plug terminal side or the side that has the wires coming out the back of the plug?
probably been answered before but if you could again that would be great thank you

oh almost for got if you could too please add a link to a good detailed obd1 ecu pinout like wire color and what that wire goes too that would be awesome thanks you guys

 

Typically wire side of connector.

Thank you spAdam!!! I feel like a dumb *** for asking such a basic question. Funny thing is I’ve been told once before just couldn’t remember.
