My recommendation? Just don’t do it.
As part of a studio upgrade, I needed to run about 200 feet of ethernet cable. Spooling the cable was an adventure in its own right as I had not planned for ethernet in the studio conduits. But, a little creativity, and I was able to route the requisite cables without compromising the studio walls.
After several hours of fishing cable, the job was almost done. All I needed to do was fit the RJ45 connectors to the ethernet cable.
I have done a lot of wiring over the years. Countless solders. Numerous patchbays. Thousands of cables.
Without a doubt, RJ45 connectors are the worst. After a couple of hours trying to fit the ends of one single ethernet cable, I was prepared to call in the telephony/networking folks.
I really did not think I could get the ends to fit properly.
I was ultimately successful. Just not too sure about the frustration factor. Although, when the cable tested positive and the signal flow worked, I had a strange sense of achievement. I wired an ethernet cable. By hand, no less.
I am the man.

Good luck. You will need it.
