I have my elm327 wifi connected but it's permanently on. Is there something I can place between the connections to act as a switch

Have you had battery issues? I leave mine in for weeks at a time with no problems. Assuming you mean a bluetooth elm327 adapter?

Yeah mine is the same in the Audi and my old Freelander. It doesn't use much power at all. Like I say, I leave mine plugged in with no issues. I personally wouldn't want to add a switch but I do know some who people have.

Battery died after not using car for 2.5 days.

Sounds like there could be an underlying issue/s. Mine is parked up for two weeks at a time sometimes and still starts no problem with OBD plugged in. A bluetooth one.
