I don't think there's much risk of chafing if you secure the bundles on either side of the bulkheads as shown in plans. I found the trick to be taking care when final-installing / riveting the side skins to be sure nothing gets "pinched". Once the side skins are riveted in place, the wires won't move (therefore little risk of chafing) if secured on either side. Wrapping the bundle where it passes through bulkheads is a good idea but might make it harder to trace a problem wire later or run more wires through the channel.
