Cant really help on diagram info as the link seems to be down at the moment but I can say this I bought 4 modbo 4 chips back when I attempted this and was no good at soldering burned up 2 of them using too hot of an iron then finally got all the wires attached to the chip looked at the super tiny points I needed to link it to on the motherboard. Promptly noped out have not returned since then. Attaining a second slim ps2 (my first was a silver model 90000) has prompted me to dig out a modbo 4.0 modchip I purchased around two years ago for $4 off dealextreme but didn't have the courage to install on my only system. But now I have a cheap practice system so I had little to lose.

Modbo 4 0 Installation Art For Kids

I don't have a lot of experience working with boards and I wouldn't call myself completely illiterate at soldering. Do you think this is safe-ish for me to attempt doing? Or should I try this later once I've gotten more experience? I'll be installing a onechip into my PSone very soon which is a pretty straight-forward and easy job if that gives you an idea of what I'm capable of doing without there being much danger of me goofin'.

  Be honest with yourself in terms of your soldering skills.
  Do you have a temp controlled / temp adjustable iron? You want to be able to use the correct amount of heat (basically just a little more than necessary) so that you don't cook the parts your soldering too or send too much heat into the area around the part your soldering to. Temps both too high and even too low can be bad. You need to be able to dial in that sweet spot tempt wise. If you have a decent quality non adjustable iron and an appropriately sized chisel tip, then you can make due.
  Have good quality rosin core solder on hand (I like the 60/40 stuff) and additional flux can help. Also a solder sucker or desoldering braid is necessary.
  Use proper technique. You need to heat both metal parts up (for example, the wire and the solder point). Your not trying to just 'flow' hot solder onto the two parts like some kind of glue. You need to heat up both elements your joining. There are different camps on soldering, some people like to tin the solder points only, some the wires only and some both. IMO as long as your tinning one of the two, you'll be fine. For someone not experienced, I'd probably lightly tin both the solder point and the wire. Solder doesn't flow into cold areas. It flows towards the heat.
  If I were you, I'd bridge some points on the board on purpose. glob on some flux, put your iron down and start flowing solder. Bridge a few. I'd recommend PCB points and not chip legs. Several of the mod chip install points are nice flat pads on the board. Use those. Then take either a solder sucker or desoldering braid and fix the mistake. The point here is that you will most likely create some bridges, it is no big deal and easily handled as long as you spot them and don't get worked up about it. When using a solder sucker, dont try to move the iron out of the way... keep it in place the whole time. Doing this made my efforts with a solder sucker improve greatly. That joint goes cold again in seconds, 2 or 3 at most.... good luck moving the iron and firing the solder sucker in time. It can be done, but it is way harder than necessary. For desoldering braid you just lay it over the solder you want to remove and use the tip of your iron to apply heat, the solder will soak into the braid.
  Above all else, take your time. Using the proper equipment with good technique, the only difference between you and a pro / more experienced modder is that they will be able to work faster and will have cleaner results. You'll get the job done, it won't be as pretty or as fast, but it's possible. As long as you don't go hulk or apply a lot of heat for a long time to any one point, you will not damage anything. The modchip may not work the first time around, you may need to go back and touch up solder joints or find mistakes you made, but you should be able to get there given enough time and effort.

  I wouldn't at all recommend this to a beginner.
