Random spare wires and things

[BryanS]

Trying to figure out what these artifacts are.

Bought a 83 k5 someone swapped a 454 into

The only thing electronic on the truck is the radio and it’s broken. There are a few random wires that I’m not useing and would just assume delete

There is also a weird solenoid on the firewall I cannot figure out

Carbon canister with an octopus worth of hoses not hooked to anything and a capped off line into the PS pump.

Any ideas advice very appreciated

I want to clean out anything I don’t need

First image- looks like knock/ detonation sensor
last image-probably plugs in transmission for TTC

maybe the weird solenoid is the low vac switch for transmission TTC
