5lb Trilene fishing string, tie the string neatly behind the spade terminal going in first, put the second spade terminal as close as you can behind the first put them inside one of those heat shink tubs you are using hold in place, and shrink them, now you run the fishing string threw the sleeve then pull the spade fittings threw cut them free of the shrink tubing and voila no problem, don't use fishing string more than or less than 5lb or you will have a big knot between the spades or to flimsy to push threw sleeve. Yours looks great just passing on a trick we use here in the shop will save you a whole lot of time ...
Not time consuming if you know how to. much easier way is to use a stiff steel or copper wire, bend the end 180deg, so you have a round head, put it through the sleeve untill it comes out of the other end, tape both wires on the stiff wire, make the connection smooth, no sharp edges, and pull the whole damn thing through the sleeve. Takes only 2 minutes, no mater how long the sleeve is
Need to ensure you use the correct sleeving. Different kinds are rated for different temperatures. Looks great but the sleeving can cause issues if you have to probe the harness if you have issues

It's a good idea to make wires look nice, but from the fire hazard side, those sleeves can easily catch on fire cause they are made from cheap plastic. I would recommend using a different type of sleeves.
