My buddy had a similar issue with a 1992 Thunderbird

We used a DMM set for current and connected in series on the positive post to the positive cable.

Then we started pulling fuses and watched the current looking for the drop off.

If you had the FSM you could narrow it down further by just looking for the 'always' hot connections..

Maybe check the door chime module? I think I have heard that causing issues ( just don't remember where I heard that)
