The key to which model year to use is what electronic adapter is available, Not all years are currently available.
The designer, builder and supplier of ALL of the needed aftermarket controllers for these EPS units is "Bruno". They all work off of the original Toyota designs, which he designed for Toyota. So all of those other listings are variations of the original Toyota concept.
You can find the current available units here on his ebay page.

For anyone who wants to do this, IF you want to build your own system, the formula to what works, what to get and where to get it is in the subject matter of this entire thread. Two threads actually BUT you need to read through it yourself.
If you do not understand it then I would advise to stay away from attempting this project because it is simply over your head.
I can't make it any clearer.
NO ONE is going to spoon feed you as if you are a pre-toddler. NO ONE is going to explain to you why wheels are round and not square, so asking certain questions really is at least a yellow caution flag if not a red flag indicating that you should stay as far away from this as possible, BUT you do have the option of purchasing a pre-built kit from one of the Pantera venders such as SAC Restorations with all of the details of their kits worked out for you.
To many that is a very good option.
In any case, sincere best wishes from me.
