I saw where someone did this but I think it was on a 1999 MAx and I have a 1996, In the Haynes manual the wiring for the two are different. Any one have the instructions on how to do this in a 1996(GXE auto).(what wires to use) I can kinda figure out the power and ground.

 

I have one on mine. I didn't do it myself. I had a local shop do it for around 50 bucks. I can check which wires go where and post it. I have a 1996 as well.

 

Just use the negative trigger wire from the shock sensor and tap that onto the hood sensor. It's right on the radiator support on the drivers side.

 

I can do this without pulling the BCM?

 

Shock sensor to a factory alarm is not good. Here is why/... The factory alarm is activated by the cylinder inside the door. So if someone turns that cylinder with a screw driver then ur alrm is off. Then your rear doors are not protected either. Just spend $200 on a Attermarket alarm like VIPER. The Aftermarket Alarm turns on ONLY with a remote and can not be by-passed like factory alarm. In 20seconds someone can scan ur code into their remote. There are more things to it so its your call. Good luck.
