Just add wiring that would circumvent the temp relay that splices straight into the light circuit.

it's an old frigidaire, I think I posted a pic a few pages back. I rewired most of it, so I do know where the light run is located, and have easy access to it (underneath). I think it goes through some sort of relay however. That's likely the way to do it easiest.
