Ok so I have a 1994 Tahoe now with a 454lsx and a 4l80E transmission and 4x4. Bought from a local guy here. So the engine is running YAY... now heres the problem. I am now trying to integrate the new LS harness on the motor with the harness on the truck so everything works ( 4x4 and all , speed, etc etc.) as well as get rid of all the ugly old wiring and whats not needed. Off the harness I have AC, Tach, Speed, ...on old one I have to get altenator, ac , speedometer, tach etc... I have everything open at the old ecm behind the glove box and new ecm and wiring under the hood. I wanted to put the new ecm inside but no room. I cannot find a diagram anywhere on this trucks wiring and am getting confused as to what I need to do to finish this wiring. Anyone have any wiring diagrams that may help? I am getting so frustrated trying to figure out where and how to tie in these last items. Thanks to any and all for any help.

um....didn't mention anything about an o2 sensor.... needing wiring help to wire new controller ecm into truck systems ecm and pull out wires I don't need in stock harness....Truck is running just need to get fans hooked in, ac hooked up, tach working , speedo working, and make sure tranny is working shifting and such properly as well as 4x4 shifting properly.
As mentioned I have the truck running, I can shift it into gear and move, of the four wires running to the transmission I haven't plugged them in yet.

That's odd, Sorry Dan. That reply was to a completely different post.
