I feel so ****ing stupid the fuse that been drawing current isn’t the ignition fuse but the I/P fuse panel, Instrument cluster, Powertrain Control Module (PCM) fuse and my cluster been going in and out.

So you think it’s the cluster causing the draw?

I thought It was so I pulled the gauge cluster and it’s still pulling current. Now I’m just looking for a wiring diagram so see what hooked up to that fuse. Found something online that said 1,7,19,25 and 31 pulled all of them still have current. So going to see if the radio and that fuse is hooked up to maybe anything together.

Fuse-27 is the 12V power for the 460 amplifiers and the factory radio. If they are working properly there should be no difference in your reading. A difference indicates that the radio or the amplifiers are pulling some amperage even though they are supposed to be turned off. I would pull the connectors off of each 460 amplifier, one at a time, and check your drain reading to isolate which is leaking power.

Well pulled the fuses connected to the maxi fuse and it lead me to fuse 39,27 the amp and the generic electronic module which leads me to power windows, both door ajar switches, I/e cluster, horn/ cigar light, main light switch, brake level switch, wiper/washer, ignition key warning switch, safety belt switch.

now that you say that I have seen people find a door switch was bad so intermittently thought the door was being opened but I believe the dome light was coming on too

Little late here but I've had a draw in my 01 since I bought it New. Finally decide to fix it this year. GEM was my draw too. I followed post 5 and it solved my problem. No adverse effects I've seen in the few months since I did it (I pulled the wire from the plug, didn't want to cut it).
