Can you make manual locks automatic?
Although it is very rare these days to buy a car with manual car door locks, you may have a used car that you want to convert to power locks. Fortunately, you can buy kits which will allow you to change your manual lock into a power lock in only a few hours.
What kind of wire does a car door lock use?
There is either a constant ground or positive wire that makes contact with either the lock or unlock wire when the switch is pushed. The idea here is to add relays that will make the alarm’s lock and unlock outputs to do the same thing the switch does. 3-wire door locks are used by a lot of Japanese cars.
If the alarm you are installing has positive outputs, then simply hook up the “85” terminals of the relays to ground (-). Please keep in mind that the diagrams apply to most GM, Chrysler’s and Fords, but not ALL, so all wires should be checked before any connections are made.
How does an alarm hook up to a door lock?
A grounded switch can also be added where the alarm hooks up to lock/unlock the doors manually. Note that the diagram is for alarms that have negative (ground) pulses for lock and unlock. If the alarm you are installing has positive outputs, then simply hook up the “85” terminals of the relays to ground (-).
How is the output of a car alarm connected?
Many of today’s alarms have a port to plug the LED directly into them. If yours does not, there will be a dedicated wire that has a positive or negative output. If the output is positive, connect it to the positive wire of the LED and connect the negative wire of the LED to ground.
