It is a ground switched circuit.

Negative door lock relay diagram. How to wire up relays and install locks on vehicles that don t come with power door locks or does not offer any analog inputs to tap you outputs from you alarm remote start on to door 5 wire. There is either a constant ground or positive wire that makes contact with either the lock or unlock wire when the switch is pushed. All of the following are true about the circuit in the diagram above except. 3 wire door locks can be either positive diagram below or negative.

The diagram below shows how to change a negative pulse to t positive using one single pole double throw spdt relay. These directed electronics internal door lock relays can get confusing. 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. Some older door lock systems found on domestic cars omit the relays and use a thicker gauge wiring instead.

This relay configuration can be used to change negative door lock output of an alarm to positive fro a positive door lock circuit or to change trunk release output to positive for a positive trunk release circuit. This is one of the most common type of door lock switch configurations found in most vehicles. Using a diagram locate the door lock relay. 12 volt neutron 32 956 views.

It contains two clamping diodes. Late model vehicles use control modules offering more features for door. Then connect to the wires that activate each relay accordingly. A positive pulse door lock circuit is very similar.
