Lo, you've said a couple times that you "know" that splicing isn't a good idea. If you've read some of the bizarre ideas on the internet about this you should disregard them. One or more splices in a wire don't have any appreciable effect if they don't come apart. So, the only problem is the inconvenience of making the splice. Anything solid, even twist 'n tape, can work, such as soldering or using wire nuts.
