Another approach to W900 wiring.

I could use a wiring diagram for a W900 that has a mechanical engine. I am removing the ecm and harness from a 93 that has a Detroit to install a newer engine. The replacement harness doesn't use the ecm to control the fan. I need to go backwards so to speak and rewire some of the fan's electrical harness. By using a truck without an ecm say like my 95 W900 with a mechanical Cat, I can adapt the wiring in the 93 to be like the wiring in the 95.

So forget about my 2 previous posts on wiring. I can sensibly remove the ecm and harness from the 93 and go to the 95 for what I need to do to get the fan working with the engine temp. and a/c.

My 95 W900 with the mechanical Cat is s/n 659321. So if anyone can get diagrams for that truck it would be a great help to me. Yes I could go to Kenworth but I no longer buy parts there unless I am desperate or forced to for some reason.

 

@spsauerland You are the man! I think I am go to go with the schematics you posted. You saved me from a whole lot of begging.
