Hello i have a 92 ford fiesta flight 1.4. I bought a shark Professional Car
Alarm which has a grounded when armed wire which say it can be connected to
an central locking interface but as I have read on websites you can use
relays to lock/unlock the central locking can anyone help?
eah you usually do if you have a remote as the current required to operate the soloniod locks is way to high for the electroics for the IR or RF remote transponder
So how do i wire the alarms grounded output when armed to the fiestas central locking?
with out a wiring diagram of both im not going to comment, i am sure you understand its diffcult to sort out without seeing it.
If i could get a wiring diagram of the fiestas central locking it might make it a bit clearer to me.
thats nice and easy, just buy yourself a haynes manual it will be on the back few pages.
I think tomorrow i will be getting one but i was looking for advice to get
a grounded when armed wire to work with the central locking since i have
taken apart the drivers door and tested the 2 plugs for the central
locking. I know the red/black is 12v constant and brown is ground constant.
The second plug the yellow and white switch polarity when lock then back
when unlock. Which i can get my head around wiring the grounded when armed
output to the central locking.
I found out if you touch the white and yellow together for 2 seconds all
doors lock touch it again they unlock.
If you send a gound voltage for 2 seconds to the yellow the doors lock if you ground the white for 2 seconds the doors unlock.
So how would you wire the grounded when armed output to the central locking without blowing fuses if someone forgets to turn the alarm off and unlocks the car with the key?
