Anyone tell me if the central locking on a UK98 turbo is "low negative". Need to know for the alarm remote central locking.

Cheers

Is it a 4or5 door?
is it a version 3 or 4
Does it have remote locking already?
If not it needs an extra motor in the drivers door!!!!!!

Its got remote central locking on now but the current alarm (scorpion) can cope with positive and negative but im changing alarms cos i haven't got shock sensors, proximity sensors or pager output. The new alarm will only do "low neg" central locking.

Its a 4 door.

Ideally i'd like to add the extra bits to the scorpion but I dont think i can do do it!

If it is approximately V-reg or newer, the central locking is a single wire system whereby momentarily cutting the trigger wire will lock the doors, and a low current pulse to ground on the wire will unlock the doors. Earlier than this will require a locking motor in the driver's door. If your alarm is only capable of pulsing two-wire locking systems, the addition of extra relays will be required for both of the above scenarios.

If that is the case, give me a ring on 0113 2441448 during office hours and I can explain or fax you a diagram of how to make an alarm with low current negative locking outputs run the lock motor you'll need to install in the driver's door.
