I have tried: taping them together, hot glueing them together and ziptying it right to the frame to prevent jiggle.

All have failed.

Right now, when I reconnect them and apply pressure, I can’t even get the engine to turn on anymore. But the speedometer still works and that signal is sent through the engine cable too.

Recently, sometimes the engine rear wheel barely rolls when I roll the bike backwards.

There are no ebike repair stores in my city.

    If the problem is in the connector (could be elsewhere as some have suggested) and if it’s like the one in the pic, then it’s likely gone. Possibly corrosion, or a defect, or loosened female side, etc. This is a HiGo connector and they’re generally very robust. The male side is likely fine. You could replace the female or both sides by buying an extension of the same HiGo type (number and type of pins), cutting it in the middle, cutting the existing connectors, then splicing the newly cut connector-wire pairs to the respective sides. You’ll have to ensure the pin arrangement is the same as in the original cable using a multimeter. If all of this sounds overwhelming - get in touch with someone who is familiar with wiring and soldering. It’s an hour tops for a person with the right tools and materials. Cutting both connectors and just splicing the wires together is also an option as some have suggested. That might be easier to do if the cable color coding is the same on both sides, but that’s far from certain so I’d say the same work for matching the pin arrangement applies.
