Schroth 4pt. Harness Install
After just completing my install, here are a couple of thoughts.
Definitely lay out the rear part of the belts to get the orientation right. That way you bend the metal mounts once! I oriented mine so that the bend is on the roof side of the bolt. Hopefully the belt is least obstructed by the seat this way.
Releasing the console via the two screws in the storage area is the way to go. Less swearing and knuckle busting.

"you simply need to disconnect the inside should belt from the lap belt so that the shoulder belts can be taken out of the seat back. "

To get the harness out of the seat back you only have to disconnect one side. I recommend the shoulder harness closest to the concole, as this will allow you to more easily store the harnesses under the seat.
The black plastic piece piece (Red arrow) is part of the tightening mechanism, that holds the belts firm in place. This is the piece you have to remove to disconnect a should belt from the lap belts.

That piece is held on with two tabs (blue arrows) that fit into the small recessed areas of the metal buckle half. Apply presssure to slide the black plastic piece in the deirection of the green arrows ( I usually do one side at a time, as you have to push pretty hard to ge the tab to release).

Once you have both sides released, you can slide the metal bar (Yellow Arrow) out of the side of the piece, and you are good to go. I strongly reccommend putting all the pieces (sans belt fo course) back together, pushing until the tabs click into place. This will keep you from losing that metal bar, as you are pretty much screwed without that piece.

HOpe that helps clear that up.

Great write-up, i just did mine tonight (these were taken out of my old car) and the install was a breeze, especially after taking the center console out.

Guys.. I just bought the sparco harness bar and two new scrothe designed sparco harnesses.. one 5 point and one 4 point and camera mount. I got the snap on kit.. was there anything else i was supposed to get?
just installed these as well!
I must say, these are well worth the money! These are very comfortable harnesses. Man I can just concentrate on my driving instead of how to pin myself back into the seat while in autox

Tim, shoot me an email or a call, i'm debating turbos.
Another necro revival:
I just installed these tonight. I DID NOT need to pull out any the the belt from the receiver/console side shoulder belt adjustment/lock in order to fit it through the stock evo 8 seat hole. It DOES fit through the hole, and quite easily. I just had to gently pull one thing through at a time, and at one point had to fold it over the make it narrower, it took about he same time as the outside shoulder strap.
On another note: due to the fact that the inboard/tunnel/ receiver mounting tab is smaller in diameter than the tab for the factory seatbelt receiver, the factory mounting bolt has a "stepped/spaced neck" on it that is too wide for the Shroth mounting tabs hole. the result was a secure Schroth mounting tab, but the inboard/tunnel receiver is a bit looser than it was before, as the bolt does not quite go a far in. Has anyone else experienced this? It seems fine enough, as it had a little bit of play before ayway. I am going to switch it to the Schroth bolt, which should work fine.
Why did I try the factory bolt? Because it had a longer threaded section. The harness comes with threeshorter bolt and one longer one. the longer one would proaby be good to use on the door sill side, as that point has the most/longest hardware, but I had already used it for the also long rear middle belt point.

the reason to remove the piece from the shoulder clip, was to get it out of the way when not using it, if not, you're always going to lean back on the shoulder harnesses. Undo the one clip, and it slides back through, out and under the seat.
