hey I haven't actually hooked it up yet, but it's basically an adapter harness. My engine will be dropped in this weekend, so I should know something either this weekend or next weekend. I'm going to attempt to use the 22RE fuse box, supposedly you can, if it doesn't work I'm gonna get a 3RZ fuse box. You still use the stock 3RZ engine harness and the 22RE dash harness. You plug both of them into the ORS harness and plug the ORS harness into the computer. There are a few hook ups that you have to make(can't remember them off the top of my head) but they're all labeled very specifically. Any idiot could hook this up.
...we need pics of everything
