Getting ready to pull my first 5.3 from the junkyard

[Kree]

Hey all! Been lurking for awhile and finally have my first question. Heading out to the junkyard to pull a 5.3 and trans this friday for my 68 C20. Other than an assortment of 10, 13 and 15mm sockets and wrenches, some pliers for coolant hoses, some elbow grease and an engine hoist... are there any other tools needed to pull the motor and trans out? Am I cutting the wiring harness at the firewall in order to keep the engine bay fusebox or can i cut at the fuse box to keep it all simple. I really dont want a bunch of stuff under the hood if its not necissary. Thank you in advace for any help, trying to make this a quick trip to the yard lol
