I used 4 pull strings per side. Broke the wire bundle up into 1/4's and slowly pulled each one thru while pushing on the other end. Lots of liquid dish soap int the bars and on the wires. The best piece of advice I can give you is if you experience issues walk away. Come back later with a fresh head.
Good luck man I did some 16 yaffes on a RK tbw and it was a bitch. Had to do the right side 2 because I popped a fuse and thought it was in the wiring. I'm sure non tbw will be easy enough tho, good luck it'll be worth it in the end
