Sorry - didn't see this until now.

Yes - e brakes are different. Perhaps you could make a little "jumper" connector, out of wire (or with a mechanical bracket of some type), to bridge the extra distance.

We might need more detail on the prop valve/brake cylinder questions. I have the brake engineering release charts at home and will check when I get there, but might need to know (or figure out) JB1/JB3/JB5/JB6 for both the donor and recipient.
