@keyzo, that was my point. The older harnesses, were a one size fits all, with caps for higher spec models, but the latest ones are being designed for each spec and packs, as the harnesses weigh a tonne, so the theory us remove unwanted wiring to reduce weight.
I Morocco,nowhere mist harnesses are made (cheap manual labour) they have boards where the harhessesxare built to spec of xar/packs.
This us why you see either pack only options, or for quite a few far east manufacturers, no options at all.
Economy of weight.
