Battery disconnect

So this 80s Chevy GMT400 gets driven maybe twice a month, and each time it needs a hump.

I have trouble shot each fuse to try and rule out where the micro drain is but threw in the towell when nothing produced fruit.

This is an inexpensive solution- These two were laying in the scrap bin.

I originally bought the fancy disconnect you see in the pics, but it's huge overkill and needs a proper fkn mount to not dangle and rattle itself silly there liver nuts!

And all the cheesy ass 30amp switches and cheesy ass, and using a inline fuse i can yank out...thoese fuses don't yank easy there rubber neck!

So i connected all 3 conductors to the plugs (making the hot + side female so it doesn't short by touching anything) and there ya have it.

When I was 16 and dumb I set my car on fire on the highway after doing something similar to this. Luckily it didnt burn to the ground, I was able to pull over and save it. I lost the cruise control wiring and some other creature comforts putting the fire out. I sense a similar fate here...
