Car Alarms: Alarm, pager car alarm, microwave sensor

Question
Hi there, I recently purchased a pager car alarm and it included a shock sensor and ultrasonic detectors, it was meant to include a microwave sensor but instead they sent me the ultrasonics anyway I have purchased a dual stage microwave sensor and I need some help installing. On the alarm brain it will only take a 3wire plug and the microwave sensor contains 4wire plug 1 extra wire for exterior warn away. Where should I connect this? And also should I get rid of the shock sensor? I heard there not reliable. Another thing I would like to hook up is a bonnet switch but I don't see anywhere to wire this up any ideas on this? Thanks

Answer
Confusing. I would contact the seller and asked
them to go over the interfacing of these products.
It does not sound as if they sent the correct equipment.

I would call them before trying to install any of this
to get the support on the sale you made.

Good luck.
