Rookie mistake.

Crimps work best with proper quality crimping tool, very few people have the proper crimping tool and substitute pliers and crush the connection making a very poor and unreliable connection.

Additionally, standard heatshrink tubing is not weather proof or water tight and moisture will destroy the connections hidden inside the tubing.

Not to mention the average backyard electrician won't have a good heat gun and will use matches or a lighter to shrink the tubing making a mess of the job..

For heatshrink tubing to work in the outdoors you must get adheasive lined tubing, it has a heat activated glue that surrounds and seals around the wire insulation making a good water and weather tight seal..

But, a good electrician will try to avoid allowing connections to be exposed to weather which means taking the connections back to the original connection box which is protected from the weather.

Inside that box, the connections are made with wire nuts, no need to reinvent the wheel. Just use the existing wire nuts inside that box and all will be fine.

True, but I do have the proper tool. I'm a retired construction electrician. And if I remember right, a box is required when the voltage is above 35 volts. On a trailer a box collects road salt and rusts.
