2003 Adventure workhorse chassis Class A

Hello folks,

I am looking for the engine and transmission harness diagram.
I went to Winnebago.com/owner portal and downloaded what they had. Although detailed they failed to add the engine ECU's and tranny info to the download.
Vehicle has a 8.1 with Allison transmission. I just need to trace some wiring and a diagram would be super sweet.

Thank you all.
