Wait, can you really use a loopback plug for this? Seems off.

A cable stripper is also useful for prepping the wires.

I thought a punchdown was for wall jacks, not connectors.

Hey, I heard the real pros use their teeth to crimp those RJ45s. Just kidding, don't try that at home!

Loopback plug? What is this, amateur hour? That's for testing, not connecting wires!

Punchdown? Nah, that's for patch panels, not RJ45s. Rookie mistake!

The cable stripper is a must-have for prepping the wires before crimping. Gotta get that insulation off first!

A crimper is definitely the way to go for connecting wires to an RJ45 connector. Can't go wrong with that.

I’m pretty certain it’s the crimper, but I wish I could recall more about the other options and their uses.

I’m leaning towards the crimper too, but I keep mixing it up with the punchdown tool from other questions we did.

I remember practicing with a crimper in lab, but I also feel like the cable stripper might be involved somehow.

I think the crimper is definitely the right tool for connecting wires to an RJ45 connector, but I’m not 100% sure.

A loopback plug? I don't think that would be used to actually connect the wires. That's more for testing the connection, right? I'm leaning towards the crimper as the best tool for the job.

A punchdown tool is definitely the way to go here. That's the standard tool for terminating wires onto an RJ45 connector. I feel pretty confident about this one.

Hmm, I'm not totally sure about this one. I know a cable stripper is used to strip the outer jacket of a cable, but I'm not sure if that's the right tool for connecting wires to an RJ45. I might need to review my notes on network cabling.

I think I'd go with a crimper for this one. That's the tool I've used before to connect wires to RJ45 connectors.
