Unless they are wires that you anticipate having to take off periodically, just terminate the small wires with the appropriate sized ring terminals. Take the nut off of the terminals and put the ring terminals on. Replace the nut and tighten. No need for a spacer. If you have several small wires, you could also replace the bolt with a slightly longer one and do the same thing.

Any auto parts store will have an adapter that adds a wingnut connection. Should be like $5.

While you're doing this adapting/modification, if the small wires don't have a fuse or circuit breaker in close proximity to the battery, add in an in-line fuse holder and an appropriately sized fuse to help prevent the possibility of a fire starting should they short out. (One important exception: the circuit for the emergency trailer breakaway brake system is often not be fused...and of course never should be switched.)

Many thanks for the ideas! I will look at them and decide which works out best.

If you really want to get creative, you can install a separate fuse block with enough spaces for each small circuit and then just run one wire to the battery to power the fuse block rather than all of the small wires. Of course the one wire will need to be large enough to handle the current draw of the combined small circuits and there should be a fuse capable of handling the load, but then each circuit is fused and you don't have a bunch of small wires attached to the battery cable. The advantage is that you can locate the fuse block anywhere that is convenient then. The disadvantage is more wiring and expense.
