Before you proceed to install the 5 point harness in your car please read the below regarding how the harness should be mounted......help from Wil Ferch, a contributor of this important safety information.
Attaching the shoulder
harness belts to the harness bar directly....is only advisable for keeping
the driver in-place for low speed sporting events..such as SCCA Solo II
competition and other types of autocross or parking lot pylon runs. For
high speed sporting events, such as encountered on racetracks as part of
Club Racing or Driver's Ed ( DE) events...the shoulder harnesses
must be anchored
to something substantial...like the rear seat belt mounting points..or
through holes drilled into the body with substantial backing ( or reinforcing
) plates. Plus , the mounting points cannot impose substantial "downward"
load on your body, to avoid spinal compression in an accident. For this
purpose, you need a harness bar located behind the seat.
It may be OK to wrap
the shoulder harnesses around the harness bar...but ONLY if it's a low
speed event like an autocross. For high speed events, as in DE's on most
tracks, the harness bar ( more appropriately named a "harness guide bar"
) is used to guide the harnesses back down to a more suitable mounting
point...like the rear seat belt anchors. The harness bar is
typically *not*
designed to withstand the substantial forces ( in bending) that would result...
if you attach the harnesses directly to the bar. If in doubt as the
suitability of mounting the harnesses to the bar, ask the manufacturer
of the bar, or the sanctioning body of your race organization. There
are commercially available bars that are not round in cross section, but
are instead built like a bridge or truss, that can take the forces of direct
belt attachment ( for example...those built by Brey-Krause...and perhaps
others) Otherwise, for round bars used in high speed events, the routing
of the harness over the bar guides the resulting impact forces back,
instead of straight down, to avoid spinal compression. For that purpose,
it
works fine.
- racing or high speed driving is inherently dangerous. The authors of
this text assume no liability with the use of the information given here..but
offer it only as consideration for the more obvious pitfalls in installing
harnesses and bars.
I installed the 5
point harness using all existing factory seat belt mounting points, no
new holes was drilled for this.
This is a picture
of where the right side harness is mounted to on the factory seat belt
anchor.

This is a completed
picture of the harness.
I didn't mount
the anti submarine belts in (don't feel like drilling hole on the floor
board), for what John uses for this is enough.
