Hello, there are 6 pages for the ECM diagrams, we will be happy to post them for you. It will be 2 diagrams for each page, top and bottom, so you can print them out and tape them together. Just give us a few minutes.
Diagrams 1,2- 3,4 - 5,6 - 7,8 - 9,10 - 11,12 go together, I will go through the OEM diagrams to verify these are correct. Any differences will be posted shortly.
Be careful when testing with certain incandescent test lights, they can pull too much current for certain ECM circuits.
There is a list of Technical Service Bulletins for the ECM.
