Default Scratching my head. Draw on battery, fuse block always has power?

hey guys im coming out of my lurking ways for some guidance. my 97 4.0 has a draw and I searched here the past week or so, I did run a meter in series and pulled every damn fuse in the jeep and could not get the draw to go down. I did however isolate the fuse block under the hood as to where it is coming from....i think

but since i was worried i had done something wrong just encase i grabbed a test light and with the vehicle off, no key in the ignition, no nothing i was still getting power to both sides of the fuses under the hood...should I be getting power there when the vehicle is off?

The ignition in the column doesnt work, the PO wired it all to a toggle button and a push button....which is where im thinking my problem could have started? would a bad ingition cylinder be stuck "open"?

Thanks in advance

Yeah of the various gadgets, half of them are switched by relays, and half of them have grounds controlled by the PCM. It might be a good idea to figure out which ground has some current.

No idea on the ignition switch.

There will be fuses that are hot, even with the key off. Look harder at the janky wiring the previous owner hacked in.

Lol the fire extinguisher is always within reach.

I swear I've pulled every relay, fuse and plugs I can. I must be missing something. Dumb question but there's only two fuse panels right? I'm back out at the shop now checking again.

Hopefully ill find something

might as well look into replacing the ignition cylinder and see if you can straighten it out that way
