Yes, really easy, remove the cable from the liner, then remove the alu nut from the end of the outer braid, slide over one of the washers, then inside the car the second washer slides over and tighten the nut. Now lay out the route you want your cable to go, make it so the bends are not too great and cut the braid at the desired length, put some tape or some shrink wrap on the cut off end to resist fraying and then slide over the metal sleeve that's already on the braid, then push the black plastic end with the locking tangs for the square throttle cable hole on the end, insert into the stock bracket
Now feed the cable into the other black plastic gizmo from the larger diameter end, that's the piece that hooks into the throttle pedal hole, feed all the way through making sure it's engaged into the end of the throttle pedal, cut the cable to length, you can be a bit off as the clevis (there are 2 in the kit, pick the style you need) that goes on next has some adjustment in it. secure the cable in the clevis with the small set screw, install the throttle lever stud on your carb/ TB if not present already, slide over, cotter pin in, eh presto you have a throttle cable
