adding additonal sensor to old alarm

Hi, I have decided to fix a few electrical issues with my OLD Clifford Sabre alarm (Installed 1993). So having looked around I have obtained a Dual Zone sensor ebay. It is this device if you are interested. JSDMV So after working the wiring in the car I came up with these options In the attached image. So I just wanted to confirm I have not missed anything etc.

Image added in above link. Didn't seem to upload into the post

The dual zone part won't work with the Sabre. If old Clifford wiring, red to red, black to black, blue (inner zone) to 0range on Sabre. Outer zone to a piezo siren. You won't need any relays. Do you have any prices on that unit?

Can you PM with how you obtained that sensor? I'm interested in buying some if it works.

Thanks for the replay - The Wiring for Clifford shock sensor is indeed red,black, orange for shock sensor. I am using the relays to work around the Sabre's single limitation. Didn't think about just connecting the outer zone to a dedicated warn away siren/peizo sounder! Considering its been in for 20 years the Clifford brain still works so I see no reason to change it out till it stops working.

If correctly installed the actual G2 brain, Sabre, Eagle etc. will last for ever.
