can someone please put up a picture of how the plugs go in(labeled) and the numbering of the pins so i can wire up my engine, thanks alot.
bottom ECU is PR3
http://www.geocities.com/b16aprelude/hondaengines.html
is how it plugs in...
they can only be pluged in one way? big clear plug in green socket, two smaller plugs in the black sockets.
is this what you wanted to know?
