ECM Pin Order

Recommended Posts

Hi Guys

Just wondering how the pins are numbered on the stock ECM? I'm guessing the sockets are J1-J4 left to right but how about the pins?


Are the numbered left to right then top to bottom? I.e. left socket/top left pin would be J1-1 and top right J1-6 the next row down J1-7 through J1-11?

Trying to make an adapter harness for the new ECU.

That seems to correspond to what I pieced together from the electrical circuit manuals for my SE. There is also a diagram in EMH.4, which I didn't know about when I created my own table...
