Use the search function, there are lots of ways to do it but most of them are wrong.

You don't want a harness if you don't have a roll cage either, if you roll the far the harness will hold you upright and your head will act as a roll cage, but with your head made from meat and bone you will be dead.

I'll take a harness in a roll over crash over a seat belt with or without a roll cage any day thanks.

As to the question from OP, the BEST thing to do, is actually grab the CAMS regs on mounting and get the angles right. As for the nut strap, you will most likely need to drill straight through the floor, and put the mount in. You can buy certified mounting plates from around the place that the loop will bolt into.

Before you drill, MAKE SURE you're not going to pierce through fuel or brake lines, or drill straight into a wiring harness.

3 point harness hence no nut strap, only correct way IMO would be to install a harness bar, you can use the bolt on the seat belt slide thing on the right side but you will need to drill a hole in the floor on the left side and use a backing plate.

Look at a few cars that have rolled over, its the top of the seat that stops it from going any further down, if you cannot move out the way its going to be your head that stops it.

Do a risk assessment on it and see what you come up with.

In my R33 I have a 4 point harness that uses 3 mounting points.

I used the following:

Front bolt for the OEM seatbelt rail for the right hand side

Rear left seat bolt for the left hand side

Made a bracket that bolts onto the parcel shelf for the rear mounts

I'd take photos when I get home, but home doesn't have internet at the moment :laugh:

Off the top of my head I think CAMS recommends a maximum of a 45deg angle from the horizontal from your shoulders (or something to that effect). Any more than that and the harness will tend to pull you down, puting extra strain on your spine (source: Eric the CAMS scrutineer at the old Oran Park drift days :D) This means that your rear mount from the rear seat belt is not ideal...

In my opinion, a harness with a OEM seat is far more effective in holding you in place that an aftermarket seat with OEM seat belts :thumbsup:

It will definitely hold you in place so you don't move around but that isn't what a harness is designed for, the seat holds you in place, the harness stops you from being thrown around in the event of a accident.

Thanks for all the advice guys i kind of got most of the harness installed except the bottom strap on the left. which i need to buy or create a plate to bolt one down.

I was originally going to use the normal seat belt my friend gave me his harness as a present so i thought i use it just for fun.

Look at the injuries sustained in crashes from front on, side on, and rear on from seat belts, and then from harness.

Then compare the number of total accidents that involve roll overs.

Even on the track, roll overs are the rarest form of accident.

Even if you don't have a roll cage, I'd rather protect myself from the most common type of injuries/accidents...

your lower left strap should be easy..

I ended up bolting mine onto my seat rail bolt as its directly opposite the bottom seat belt bolt and goes along the transmission tunnel unlike most other skylines that bolt to the floor..

Hope that made sense.. Basically to summarise.

bottom left strap - left rear seat rail bolt

bottom right strap - bottom seat belt bolt.

shoulder straps. bottom rear seatbelt bolts or rear child restraints or harness bar ( whichever is best location or available)

If i remember ill take pics of mine tomorrow

You are only going to be using this on the track correct?

If it isn't engineered and certified, and you're using it on the road, you can be booked for it.

In my experience it's a bad idea to use a harness on the road anyway. In combination with my dark tints and my low mounted Sparco Sprint V, blind spots get quite large and only get larger if I can't move my body :laugh:

      I dunno about that as a blanket statement. Pitwork is Nissan's "Nissan genuine" thing, and for stuff like timing belts, I have found them to be excellent. Of course, for things like oil filters, you always use proper trusted brands anyway, not whatever the OEM has taken to using.

      Ahhhh... If you were putting 12V to the led in there, that's likely made it very unhappy. Chances are how you put power, was 12V across an LED that's meant to only have about 20mA through it at peak, and a forward voltage of about 1.8 to 2.4 volts. That circuit is likely only a 3V3 circuit, and will have a resistor in series with the led too. That's my guesstimate on that light, without having touched one.

      Another vote for installing them and see how you go.  I mean, you already own them, why would you not fit them?

      I have had too many of those over the years, my cars have a toolkit or at minimum a cheapy multi tool thing because its too easy to be snookered by some stupid plastic clip that stops you checking the battery terminal isn't loose.

      Basically, if there is a part# on the nissan catalogue, it is a genuine part. There is a thing called "new old stock" which is stuff made years ago but never sold (or landfilled), but it is super hit and miss what you can buy. Other than some expensive Nismo stuff there is nothing new being made that suits these cars. The only time to be a little careful is (mostly in the US I think, but maybe Japan too), Nissan started rebranding some cheap crap maintenance parts like oil filters as "Pitworks"; stay away from them, if you are buying cheap just buy whatever the local car parts shop carries The three part numbers have an explanation on Amayama: 0V005 is auto, base style 0V015 is manual 0V505 is auto, hectic momo branded ones, maximum F&F points there!
