The 2 wiring setups do the same thing, the Hewitt harness is fitted with factory style plug harnesses with no cutting required. Slyfoxes setup requires cutting and splicing but saves around $100.

Is the Slyfox still working well for you? Do you know how the slyfox system is different from the Hewitt system? One is $48 the other is $190.
What determines whether you need the block off plates or not?
Far as I can tell if you do the bypass you should also do the plates. Sly Fox works differently but not exactly sure how. Working great. Only issue was the wire was a little short. I extended it with some wire I had laying around. I contacted Sly Fox and he promptly sent me another wire. Let him know you have a lc or lx and you need an extra long wire. The Hewitt system comes with the plates. Sly fox does not. Hewitt is the cheapest place to get plates.

Not wanting to spent $200+ on the Hiwett method. I just found a writeup on the system. And with a few $20 of parts I made my own bypass as the Hiwett system. Without the bypass plate. But for my code I didn't need the bypass plate. Here is a link to it. But you need a Telegram account to get it. I'll link it when I get a chance.
This bypass does exactly what the slyfox system does. Btw there is slight modification to the instructions u see here.

If someone brings me or any shop a 100 series with S.A.I. issue(s). I'm/they're legally obligated to correct the issue if I/they take on the job, without bypassing. We can only bypass the S.A.I system, if vehicle is for off road use only. Although it plays such a small part in reducing pollution, it does play a roll and is required to be in good working order. So I'm looking into why they fail and what we can do to mitigated failure.
@BuckeyeScott I'll see if i can help you through this issue, as time permits. I'm working on somewhat similar recurring code.

Note: Toyota does have a TSB out, which requires replacing all components of the S.A.I system.

S.A.I. Filter Modification, in VVT engines. To prevent its failure! Alert Alert!
We've a $2.00 part in the S.A.I. (secondary air injection) system of the VVT engine, that is taking-out ~$7,000.00 $15,000 $25,000 (inflation) in parts. WOW! I've a very easy and cheap WORK AROUND. You are going to love this ;) This thread is dedicated to the 4.7L 2UZ-fe VVT engine, in the...

Do you know if Slyfox is still making/selling these? Do you have a link to his ebay page? I'm coming up empty. Thanks in advance!
Disregard, I found him, sorry for the thread clutter!
