Give yourself some more room with an EL wire cable extender. This cable has a 2-pin JST SM plug on one end and receptacle on the other. Use it to extend the reach of EL wire, panel, tape, etc. The cable is a meter long, you can of course snap more together if necessary, or cut and re-solder it if you need to shorten.

Because this is meant for EL wire extending, and EL is not 'polarized' we don't guarantee that that the plug and receptacle have 'matching' wire polarity. If you're using this for DC power or signal, triple-check the polarity before plugging it in!
