Agree with this. The fuse box and ECM are mounted on the driver's side inner fender. There's no extra wire to go anywhere else. If you re-engineered the harness, you'd probably find that many of the wires will reach the cab because you're using a different route, but some of them will definitely be too short.
To answer your question about how much to lengthen the wires. If you leave the bulk of the harness as-is, and just turn the main pigtail of wires toward the firewall, I'd guess you need at least two more feet to get the ECM into an out of the way place in the dash. That would be minimum, but I haven't actually measured.
I'm simply putting my fusebox and ECM on the inner fender, where it's supposed to be.
