This 2002 Toyota Avalon keeps draining the battery if it sits for more than a few days.
Owner is ready to put a kill switch on the battery.
He wants the problem diagnosed, and if possible repaired if it doesn’t break the bank.
Let’s follow the logical approach and see what the culprit is.

They actually make fuse taps, that are very inexpensive, and keeps the replaceability of the fuse.
That was a good solution to the customer's problem. Great car with silly extras causing problems. Nice Job Ivan.
Oh yea.. few parts required
Really clearly presented and thank you.
Cannot you use a seperate say 9v battery to the constant + to the cluster, keeping the settings and charging this battery while driving? Retaining the settings for a couple of weeks when not driven?
I might have added a note inside there for any future mechanic.
I have a CM 70 just like yours. Its a very old unit but I still use it.
Good trouble shooting. I'd put a relay wired off ACC to drive the multi display.
you probably already know this, but they sell fuse taps that would be a bit smaller than that fuse holder thing you put together.
There are connectors to piggy back on a fuse in the holder.
