I have access to a green lee cable tug'er ... ( capstan winch )
but any SLOW pulling method will work , I use a liberal amount of Ideal 31-378 Aqua-Gel II Pulling Lubricant . Get help at each end and go slow... YMMV

Go slow especially if you are pulling smaller control lines you can burn
the jacket or worse if there are bends, edges etc. Having someone feed
the cable in would be nice too.
