pcm wiring
Hi does anyone have 2001 international 3800 thomas e444t wiring diagrams. I am trying to diagnose a weird power problem. Lack of power and tune ability. I don't want to go crazy just simple modes. Christopher since you have a lock up tranny this might be of interest to you
My aillison 545 will not like more power so it must go.

thanks Joe

I have the whole OnCommand book that has the 444E wiring in it.. its a program tha runs on windows.. wonder how I can get it to you..

ha! im one of the lucky ones who's bus came from the south and has no EBPV :)

I posted a couple diagrams on another thread recently that had to do with issues in getting power to the user's ECM.. their bus had issues not starting... we figured the power relay wasnt getting powered up.. go to page 5 and 6 in this thread.. there are some diagrams I posted plus a PDF another member posted with some info in it..

see if that helps a little?

I should add that the circuits are numbered... if you pull back the outer jacket of the harnesses.. there will be numbers and letters on the wires.. 13E, 13F etc. these correspond to circuit numbers listed in the diagrams.. so marking on the diagram. 97H and then under it 18PK. means circuit 97H. is an 18 gauge pink wire.. and 97H will be stamped on the wire itself... its sometimes hard to find but its there (and saved my ass a few times)..
