Anyone know a source for the 2008 F53 chassis wiring diagrams?

They're available online from the Winnebago website. Here's a link to the index page:

Thanks for the information. I can sort through all the prints and see what is applicable to my unit. The index looks like it contains the data I want. I think this will help alot. Thanks for your help.

Hikerdogs,
I can't find the Ford chassis diagrams on the Winne site. I found the diagrams for the coach, but not the chassis. Wherever the coach wiring connects to the chassis wiring, it says "see chassis manufacturer wiring diagram" or something like that. The Ford side of the wiring is not shown.

Me too! Couldn't find them. Went to www.helminc.com and obtained a 72h access to the 2007 F53 chassis (2008 isn't available yet) for $9.95. I was able to print about 125 pages of the Incomplete Chassis Wiring Diagrams. I'll use these until the 2008's are available. I believe the basic wiring harnesses have not changed drastically - wiring upgrades are typically an iteriative process, at least in the industry I work in. The few spot checks I have made seem to confirm that the 2007 will work fine for the interium.

Sorry about that. I should have looked closer when it said "Chassis Wirirng Diagram".

I bought a set of Ford Workshop manuals on CD several years ago when got our coach. They were on e-bay for about $25.00 if I recall correctly. They are the originals from Ford not aftermarket ones. The official title on the CD's is "Ford Motor Company - 2001 Workshop Information". There's one CD for Cars and another for Trucks (including the F53 stripped chassis).

I looked on e-bay today and there are several hundred Ford workshop CD's still for sale. I didn't look to see if the specific ones you're looking for were there.

At the time I bought mine I had to buy a complete set of manuals for trucks and cars. There were no manuals available for a single model car or truck.

Hope this helps.

You can rent a digital copy of any year F53 chassis service manual at helminc.com, schematics included. It costs about $8 for a week or $20 for a month. You can print copies of pages but be ready with about a ream of paper if your going print the whole thing.

The regular service manual does not include emissions related stuff. It is separate.
