I cannot give you the whole schematic, it is copyright material and must be purchased from a dealer.

However, if you only need help with a particular circuit, I can help you with that group.

Where are you having trouble?

What is wrong with this machine?

Customer: replied 29 days ago.
We pulled the transmission and we are putting cab back on and have a few wires we need to know where they go
Expert:  catmastertech replied 29 days ago.

Where are they located? Under the cab or the back or the cab?

Normally, most connections will only go one way.

Do you have any wire numbers?

Customer: replied 29 days ago.
Both and no I'm not on site currently
Customer: replied 29 days ago.
Also I have received diagrams on this site before thru media fire
Expert:  catmastertech replied 29 days ago.

I was warned if I share another copyrighted schematic I would be removed from this site. Once was enough for me.

Hear is the transmission wiring and the three cab connectors. Normally, I never mark these as they only fit one way. Same cabs have other wires for options hanging underneath the cab and those are usually one way fit. The tricky one was the transmission connectors as the pigtail could reach other locations.

See the attachments below.

Where does this go on 826 cat compactor
Expert:  catmastertech replied 29 days ago.

Sorry for the late reply. I work during the day and have little access to the website.

That is the blower for the roof mounted precleaner of the air conditioner outer air filter.

It fits on the end of the roof mounted filter and will have a two wire harness run with the A/C lines to the roof mounted condenser unit.

It will be a long harness with a small two pin connector and the roof mounted condenser will have a larger connector It may have four pins in it. This is not shown on the schematic as it is a special order option.

Let me know if you need anything else.

I am here most nights after 7 eastern time and check the site until midnight.
