Righty hoe, ive just bought a HORNET 745T 2-way alarm system for the B and i have successfully wired in the main part of the alarm i.e. lights, siren, door switches and sensors but now i have to wire in the door lock harness that will control the door actuators and central locking system, now my car already has central locking, 97 Corsa Sport B, I need to know what type of door lock wiring i have? There is about 8 choices :
(1) Three-wire (+) pulse controlling factory lock relays.
(2) Three-wire (-) pulse controlling factory lock relays.
(3) Direct-wired reversing-polarity switches.
(4) Adding one or more after market actuators. (doubt it to be this)
(5) Electrically-activated vacuum systems.
(6) One-wire systems - Cut to lock, Ground to unlock.
(7) positive (+) multiplex
(8) Negative (-) multiplex
Now that is pretty confusing to say the least so who ever can point me in the right direction will have earned them selves a burger and beer at PVS09.
Please people don't guess
