You should try to determine what is not working. For example, you could have something as simple as a blown fuse. Perhaps its more than that but check the following.
Number 1, when you press the switches for the tabs, do you hear the pump running? Have yo checked that the pump has oil?
Is the pump relay getting 12V? Is the ground OK.
it may be you need a new system or just a simple fix.
Bennett has pretty good technical support and testing advice.
To answer your question, both Lenco and Bennett have electric options. Bennett may have a electric upgrade option that might allow you to use the existing tabs,
