Crimping The Connectors

See:

for how I did it on my SO3 — on the Pro it was that and more of the same — the big thing is, secure the wires exiting the drag chain, then constrain the connectors so that they don’t move, but also so that they’re not touching — you want to be able to feel each after the machine has been on for a while so as to determine if they are heating up due to a faulty connection.
