I want to put a 5 or 6 point harness in my rig, as I don't have airbags. i am super new to this kind of think. what do I need, and how do I do it? I know i need a roll bar to tie the harness to. but in I'm having trouble finding one. I have a budget of 1500. thanks in advance.
Do a search on the proper way to mount and tie in harnesses. The strap angles are critical in a collision. I've run 5 point harnesses on my street vehicles and find them a bit too restrictive. On my desert trucks I wanted to be secure and didn't have to move much. My rock crawler, the shoulder harness got in the way of me looking out the door at the wheel.
As I said, there's lots of good info on the proper way to tie them in if you haven't already done so.
A four or five point harness system requires the 2 or 3 additional attachment points. Some seats have shoulder harness attachment points built into them. Pretty common to use a roll bar to attach the shoulder straps. The center attachment for a 5-point system will likely require drilling through the floor and adding a backing plate. The center strap is pretty uncomfortable for any length of time. It gets old quickly.
Thinking outside the box here, but consider this. You might be able to find some old aircraft seats, which are built with a five point harness. The shoulder straps are on inertial reels, which allow you to move freeing in normal conditions and hold fast when needed. There are tons aircraft in the desert southwest waiting to be picked apart. 737 seat are manually adjusted and require no power. Airbus seats have motorized adjustment and are much more comfortable than the 737 seats. Both are pretty wide, so they might not fit? Smaller corporate/business jets or King Airs have narrower seats though.
