Bumper/airbag question
 

I am planning on building custom front/rear bumpers for my 99 XJ. Is the
airbag system part of the stock bumper?

Re: Bumper/airbag question
 

I do not think it is. I believe the air bag trigger is a decellorometer
thingie that actually lives in the area between the fenderwells and the
firewall. You want the deployment mechanism to be protected from direct
impact because it could become damaged beyond the point of being useful
before it ever tells the airbags to deploy, if it is placed further back on
the frame (ie, closer to the firewall) then it will be protected enough to
deploy the airbag before it is destroyed.

The Airbag Control Module is located at rear under console:

Where are the crash sensors located? That is the question.

Jeff, do you see any sensors marked on the diagram?

No, but my BMW has a similar diagram that also shows the sensors. I suppose
the "sensors" could be an integral part of the controller, but normally they
are a triple-, or maybe only a double-redundant system that contains
multiple sensors. Having a diagram with no sensors is what raised the
question.

Re: Bumper/airbag question
 

the stock bumper is worthless weighs about 25 lbs 40 if you include the tow
hooks.
(don't forget to tie the new bumper into the front tow hook mounting areas)

Re: Bumper/airbag question
 

15 pounds of tow hooks? That seems a bit much.

AFAIK the ACM functions in this manner, there are no external "crash sensors"
per se.

I think that is what Bill is saying.

My limited experience with airbags is that there should be some sort of
redundantcy built in on the sensors because a single sensor could be
damaged/destroyed before it can deploy the airbag. My BMW has multiple
sensors. Certainly a single sensor could be used, and in this case it could
be housed in the control module, I just didn't consider this possibility
earlier.
