Attaching MOMO 4-point harness?

I just purchased an unused open-package 4-point MOMO harness that attaches at the top to my harness bar. However, it didn't come with instructions and I'm unsure where to attach the two bottom straps. Seat bracket? Lower seatbelt on the outside and something else on the inside? I plan to keep my stock shouldber belt installed as well for normal use.

Yes, I do realize that MOMO has recalled a number of their harnesses; I don't believe (from looking at the tag) that this was one of those models, and I don't plan to race with it - just autocross and such.

Also, anyone know what the lifespan is on a harness?

Thanks.

I think there is a company that makes a small metal bracket that fits behind the stock belt mounting points and allows attachment of the harness belts to it. I'm not sure who makes it tho. Might be Barclay Kruse or something like that. I know I have seen mention of it on www.corvetteforum.com. I took my seat out and mounted the t-brackets for the lap belts (harness ones, not the GM ones) under the rear seat mounting bolts that come up through the floor. Then I put the seat back on and bolted it down. I know this isn't the strongest place to do it. If you wanted it more strong you could take those bolts out and fab up a piece of metal plate to reinforce that area and put new stronger bolts through. I always buckle my stock belt over my harness when I head out. A friend flipped his Grand Sport a couple years ago on a high speed event and he was left hanging by his harness. He had mounted his the same way I did. He said it was a pretty hard flip and his didn't come loose. As far as dated harnesses go. Yes, they are dated. If you enter in a class that requires harnesses the tech inspection should look at the date to verify it isn't too old. If you are in a stock class that doesn't require harnesses I don't think it should matter.
 
does the sholder harnes have clips or just the belt?
i bought the brey krause harness bar and lap belt mounts. the outside lap belt mounts come with the harnness bar and the inside lap belt mount is sold seperately. the sholder belt attaches by wraping around the harness bar and back through the clip provided. the lap belt has to be a clip on type to attach to the brackets in the kit. you can still use the factory belts any time you want. i purchased them from northstar motorsports in illinois.

if you want i can scan in the directions
 
Never mount your harness to any part of the seat. Use the stock seatbelt mounting points for the lap-belt. Real easy if you won't use the seatbelt anymore. But if you are, you can fasten both the harness and seatbelt using 1/4 or 1/2" longer bolts. Make sure they're Grade 8 bolts and use hardened washers to space things out a bit. Don't put both under the stock bolts though- you won't get enough threads in there.
 
The harnesses actually came with a bag of bolts, so maybe they are supposed to replace the stock ones (been out of town, haven't had a chance to look yet). I called MOMO; they're apparently out of the harness business in the US because of the recall on their race-prep models (3" web). The 2" web I got is fine, not recalled, and also apparently has no end-of-life other than replacing if in an accident. But they don't support them any longer and don't have install directions.

I don't plan on running anything yet that *requires* harnesses; I find I slide a bit on the leather seat surfaces and just wanted to be more secure.

The straps are all bolt-on rather than clip-on.

Thanks for the suggestions.

Update: RD Racing (www.r-dracing.com), makers of the CrossBar and CamberBar, have an install kit for 4-point harnesses. $30 for both seats, and they say it requires no drilling. Seems a bargain if true. They also sell a bar for attaching a fire extinguisher and anti-sub strap that mounts in front of the seat brackets.

I may wind up with their entire catalog on my car :) ! They make neat stuff and are very good about answering questions and offering suggestions.

Rich, "they" is DAVE COOPER and he basically does it all himself. The man puts in some hard hours because he's got a day job to see to as well. My hat goes off to Dave and the work he's done for the Corvette community, a lot of it made possible by personal testing on his own car. :upthumbs
