Assuming that you've installed the new wiring harness to the fuse block and fitted new fuses plus also connected every ground wire in the harness to appropriate ground points, I would connect the probes of a digital voltmeter (set on "buzz" or "tone" option) across the wires which connect to the device at the device you want to operate, then operate the corresponding switch. If you get a tone or buzz from the meter when you operate the switch, you're good to go.
Example: horns...find the horn wires where the horns will be. Connect the meter (set to buzz or tone) probes to the horn wire connectors. Press the horn button....meter should buzz.
Sounds tedious but should go smoothly. ..hopefully you have a,wiring diagram.
