I am currently updating electrical of our coach and making annotations on the schematics of all changes because...well I am getting older. I have scanned and made files of all the original schematics, including air, King, etc. and wire identities as well as Allison codes for my 97 270. It appears to be the same loom for the 270 as the 295 and 320. I would be happy to send you the file if you PM me. Please be advised this is NOT a copyright violation if you own a coach. I won't start sending until Monday AM.
One other note these files can be printed out in a larger format at FedEx office or similar.
Great. Sending message
Note - the PM system does not accept attachments, so you'll need to use your regular e-mail for this.
If not too large a file (less than a few M) you might consider uploading it to the Media-> Files section of the forum. Once and done and folks can download it.
