working through shop manual checklist for nostart condition. i noticed the wire colors in the ecu harness (a,b,c,d) do not all correspond to those specified in the shop manual. some do but some don't. anyone find the same with their car? as noted in the title, this buick is built in canada.

thanks,
dgc
 
What year? 86?
@pacecarta and a few others have posted about this before. What you are seeing is not isolated.
 
no need to search for post
if for example the wire doesnt match what the ecm pinout shows --> ignore it , that wire whatever it is goes to what the pinout says it is and should not take any extra brain cells to figure out
the shop manual is for 87 and may (does ) differ on an 86
in the pinout chart and the emmission diagrams you can clearly see what wires go where on their connector and to where they go on ecu and ignition module
