I blew my engine about a year ago and got it swapped with a rebuilt 350 5.7L from the same year it has 10k miles on it now I had it swapped out about 2 months ago right now whenever I have the battery connected the dash lights stay on and kill my battery. I can start the truck fine and my radio and gauges all work but when the Key is off and out the radio shuts off the truck stays running and dash lights stay on and I have to undo the battery to shut off the truck I have no idea what else to do I feel like I’ve tried everything I replaced my ignition switch already

Punctuation helps a lot.
Ignition switch?

I already replaced it and it didn’t fix anything

Is this for the 95 Burb? If so, I have the factory info for it.

yes it’* a 1995 gmc suburban slt 5.7L 350 tbi

Look at the under hood fuse box and see if you can spot any green death. Both sides but most likely underside.

I didn’t find any corrosion or rust

Try this one.

I’m gonna be honest I don’t know what I’m looking for here
