I am getting ready to replace the glow plugs on my 2006 F250. From my understanding, without taking off the cab, it is easiest to go through the wheel well. Is this completely true? Also, I will be replacing the harnesses since I have read that the old ones will most likely break from removal. Is there one side that is easier to do than the other? Because I would like to start with that side first. Any other tips or tricks?

Yes the wheel well is the best option
Yes buy both harnesses
Driver side is slightly easier IMO
Use a piece of tie wire to pull the old harness off
Watch the video above!

I bought one of those tools also, but even when being careful and dowsing the harness in WD40, a few of them still broke. So definitely buy the two harnesses and don't worry about damaging them when removing them.

I had a few showing as bad when pulling codes, and still had a code after replacing everything so needed to replace the GPCM also.

Pretty easy job compared to the injectors, which I did a month or so after the glow plugs.
